Health informatics - Digital imaging and communication in medicine (DICOM) including workflow and data management (ISO 12052:2017)
This document, within the field of health informatics, addresses the exchange of digital images and
information related to the production and management of those images, between both medical imaging
equipment and systems concerned with the management and communication of that information.
This document facilitates interoperability of medical imaging equipment by specifying:
— for network communications, a set of protocols to be followed by devices claiming conformance to
this document;
— the syntax and semantics of Commands and associated information which can be exchanged using
these protocols;
— for media communication, a set of media storage services to be followed by devices claiming
conformance to this document, as well as a File Format and a medical directory structure to facilitate
access to the images and related information stored on interchange media;
— information that is to be supplied with an implementation for which conformance to this document
is claimed.
This document does not specify:
— the implementation details of any features of the DICOM standard on a device claiming conformance;
— the overall set of features and functions to be expected from a system implemented by integrating
a group of devices each claiming conformance to this document;
— a testing/validation procedure to assess an implementation’s conformance to this document.
This document pertains to the field of medical informatics. Within that field, it addresses the exchange
of digital information between medical imaging equipment and other systems. Because such equipment
may interoperate with other medical devices and information systems, the scope of this document
needs to overlap with other areas of medical informatics. However, this document does not address the
full breadth of this field.
This document has been developed with an emphasis on diagnostic medical imaging as practiced in
radiology, cardiology, pathology, dentistry, ophthalmology and related disciplines, and image-based
therapies such as interventional radiology, radiotherapy and surgery. However, it is also applicable to a
wide range of image and non-image related information exchanged in clinical, research, veterinary, and
other medical environments.
This document facilitates interoperability of systems claiming conformance in a multi-vendor
environment, but does not, by itself, guarantee interoperability.

Informatique de santé - Imagerie numérique et communication en médecine (DICOM) incluant le déroulement des opérations et la gestion des données (ISO 12052:2017)
Dans le domaine de l'informatique de santé, le présent document aborde l'échange d'images numériques et d'informations relatives à la production et à la gestion de ces images, entre un équipement d'imagerie médicale et les systèmes concernés par la gestion et la communication de ces informations.
ISO 12052:2017 facilite l'interopérabilité de l'équipement d'imagerie médicale en spécifiant:
- pour les communications réseau, un ensemble de protocoles devant être suivis par les dispositifs revendiquant la conformité au présent document;
- la syntaxe et la sémantique des commandes et les informations associées pouvant être échangées à l'aide de ces protocoles;
- pour la communication par support, un ensemble de services de stockage sur support devant être suivi par des dispositifs revendiquant la conformité à ce document, ainsi qu'un format de fichier et une structure de répertoires médicaux facilitant l'accès aux images et aux informations associées stockées sur un support d'échange;
- les informations qui doivent être fournies avec une implémentation pour laquelle la conformité à ce document est revendiquée.
ISO 12052:2017 ne spécifie pas:
- les détails d'implémentation de toutes les caractéristiques de la norme DICOM sur un dispositif revendiquant la conformité;
- l'ensemble des caractéristiques et fonctions attendues d'un système plus vaste mis en ?uvre en intégrant un groupe de dispositifs revendiquant chacun la conformité au présent document;
- un mode opératoire d'essai/de validation visant à évaluer la conformité d'une implémentation au présent document.
ISO 12052:2017 a trait à l'informatique médicale. Dans ce domaine, il s'intéresse à l'échange d'informations numériques entre un équipement d'imagerie médicale et d'autres systèmes. Dans la mesure où de tels équipements peuvent interopérer avec d'autres dispositifs médicaux et systèmes d'information, le domaine d'application du présent document doit recouper d'autres domaines de l'informatique médicale. Il n'en traite cependant pas toute l'étendue.
ISO 12052:2017 a été élaboré en insistant sur l'imagerie médicale de diagnostic telle qu'elle est pratiquée en radiologie, cardiologie, pathologie, dentisterie, ophtalmologie et disciplines associées, et sur les thérapies basées sur l'image, telles que la radiologie interventionnelle, la radiothérapie et la chirurgie. Toutefois, il s'applique également à une large gamme d'informations en lien ou non avec l'image qui sont échangées dans des environnements cliniques, axés sur la recherche, vétérinaires et autres.
ISO 12052:2017 facilite l'interopérabilité des systèmes revendiquant la conformité dans un environnement multifournisseurs, mais ne garantit pas, par lui-même, l'interopérabilité.
Zdravstvena informatika - Digitalno slikanje in komunikacija v medicini (DICOM), vključno z upravljanjem poteka dela in podatkov (ISO 12052:2017)
Ta dokument v okviru zdravstvene informatike obravnava izmenjavo digitalnih slik in informacij, povezanih z izdelavo in upravljanjem teh slik, med medicinsko opremo za slikanje in sistemi, ki skrbijo za upravljanje in posredovanje teh informacij.

– skupino protokolov za komunikacijo prek omrežja, ki jih morajo naprave, skladne s
tem dokumentom, upoštevati,
– skladnjo ter pomen ukazov in z njimi povezanih informacij, ki jih je mogoče izmenjevati z uporabo
teh protokolov,
– (v okviru izmenjave predstavnostnih vsebin) nabor storitev za shranjevanje teh vsebin, ki jih morajo uporabljati naprave, skladne s tem dokumentom, ter obliko datotek in imeniško strukturo medicinskih podatkov za lažji dostop do slik in z njimi povezanih informacij, ki so shranjene na nosilcih podatkov za izmenjavo,
– informacije, ki morajo biti podane pri uvedbi, ki je skladna s
tem dokumentom.
Ta dokument ne določa:
– podrobnosti uvedbe katerekoli funkcije standarda za digitalno slikanje in komunikacijo v medicini (DICOM) v skladni napravi,
– celotnega nabora funkcij, ki se jih pričakuje od sistema, sestavljenega iz skupine naprav, ki so skladne s tem dokumentom,
– postopka preskušanja/vrednotenja za ocenjevanje skladnosti uvedbe s tem dokumentom.
Ta dokument je povezan s področjem zdravstvene informatike. V okviru tega področja obravnava izmenjavo digitalnih informacij med medicinsko opremo za slikanje in drugimi sistemi. Ker lahko taka oprema deluje v povezavi z drugimi medicinskimi napravami in informacijskimi sistemi, se mora področje uporabe tega dokumenta povezovati z drugimi področji zdravstvene informatike. Kljub temu ta dokument ne zajema vseh ustreznih področij v celoti.
Ta dokument je bil pripravljen s poudarkom na diagnostičnem medicinskem slikanju, kot se uporablja v radiologiji, kardiologiji, patologiji, zobozdravstvu, oftalmologiji in z njimi povezanimi disciplinami, ter pri zdravljenjih na podlagi slik, kot so intervencijska radiologija, radioterapija in kirurgija. Kljub temu se uporablja tudi za
širok nabor informacij, povezanih s slikami, in drugih informacij, ki se izmenjujejo v kliničnem, raziskovalnem in veterinarskem okolju ter drugih zdravstvenih okoljih.
Ta dokument omogoča lažjo interoperabilnost sistemov, ki so skladni za uporabo v okolju s sistemi drugih ponudnikov, vendar sam po sebi ne zagotavlja interoperabilnosti teh sistemov.

0 Introduction
Digital Imaging and Communications in Medicine (DICOM) is the standard for the communication and
management of medical imaging information and related data.
0.1 History
With the introduction of computed tomography (CT) followed by other digital diagnostic imaging
modalities in the 1970s, and the increasing use of computers in clinical applications, the American
College of Radiology (ACR) and the National Electrical Manufacturers Association (NEMA) recognized
the emerging need for a standard method for transferring images and associated information between
devices manufactured by various vendors. These devices produce a variety of digital image formats.
The American College of Radiology (ACR) and the National Electrical Manufacturers Association
(NEMA) formed a joint committee in 1983 to develop a standard to:
— promote communication of digital image information, regardless of device manufacturer;
— facilitate the development and expansion of picture archiving and communication systems (PACS)
that can also interface with other systems of hospital information;
— allow the creation of diagnostic information databases that can be interrogated by a wide variety of
devices distributed geographically.
ACR-NEMA standards Publication No. 300-1985, published in 1985, was designated version 1.0. The
standard was followed by two revisions: No. 1, dated October 1986 and No. 2, dated January 1988.
These standards publications specified a hardware interface, a minimum set of software commands,
and a consistent set of data formats.
ACR-NEMA standards Publication No. 300-1988, published in 1988, was designated version 2.0. It
included version 1.0, the published revisions, and additional revisions. It also included new material
to provide command support for display devices, to introduce a new hierarchy scheme to identify an
image, and to add data elements for increased specificity when describing an image.
In 1993, ACR-NEMA/Standard 300 was substantially revised and replaced by this document,
designated Digital Imaging and Communications in Medicine (DICOM). It embodies a number of major
enhancements to previous versions of the ACR-NEMA standard, as listed below.
— It is applicable to a networked environment. The ACR-NEMA standard was applicable in a point-to-
point environment only; for operation in a networked environment, a Network Interface Unit (NIU)
was required. DICOM supports operation in a networked environment using the industry standard
networking protocol TCP/IP.
— It is applicable to offline media exchange. The ACR-NEMA standard did not specify a file format
or choice of physical media or logical filesystem. DICOM supports operation in an offline media
environment using industry standard media such as CD-R, DVD-R and USB and common file systems.
— It is a service-oriented protocol, specifying the semantics of commands and associated data, and how
devices claiming conformance to the DICOM standard react to commands and data being exchanged.
Specified services include support for management of the workflow of an imaging department. The
ACR-NEMA standard was confined to the transfer of data with only implicit service requirements.
— It specifies levels of conformance. The ACR-NEMA standard specified a minimum level of conformance.
DICOM explicitly describes how an implementor must structure a Conformance Statement to select
specific options.
In 1995, with the addition of DICOM capabilities for cardiology imaging supported by the American
College of Cardiology, the ACR-NEMA Joint Committee was reorganized as the DICOM Standards
Committee, a broad collaboration of stakeholders across all medical imaging specialities.
0.2 Principles
© ISO 2017 – All rights reserved v
---------------------- Page: 11 ----------------------
SIST EN ISO 12052:2018
ISO 12052:2017(E)
0.2.1 Global applicability and localization
DICOM is a world-wide standard that can be used in every locale. It provides mechanisms to handle
data that support cultural requirements, such as different writing systems, character sets, languages,
and structures for addresses and person names. It supports the variety of workflows, processes and
policies used for biomedical imaging in different geographic regions, medical specialities and local
practices.
Localization to meet the requirements of national or local health and workflow policies can be done
without deviating from the DICOM standard. Such localization may include specifying code sets (e.g.
procedure codes) or profiling data element usage (both specifying locally-allowed values, and making
elements that are optional in the DICOM standard mandatory for local use).
Localization and profiling can be specified in a number of mechanisms outside the purview of the
DICOM standard. One such mechanism is Integration Profiles from the Integrating the Healthcare
Enterprise (IHE) organization. It is important that Profiling adhere to the concept of non-contradiction.
A Profile can add requirements but should not contradict DICOM requirements, as that would make it
impossible to comply with both DICOM and the Profile.
0.2.2 Continuous maintenance
The DICOM standard is an evolving standard and it is maintained in accordance with the Procedures of
the DICOM Standards Committee. Proposals for enhancements are welcome from all users of the DICOM
standard and may be submitted to the Secretariat. Supplements and corrections to the DICOM standard
are balloted and approved several times a year. When approved as Final Text, each change becomes
official, is published separately, and goes into effect immediately. At intervals, all of the approved Final
Text changes are consolidated and published in an updated edition of the DICOM standard. Once changes
are consolidated into an updated edition of the DICOM standard, the individual change documents are
not maintained; readers are directed to use the consolidated edition of the DICOM standard.
A requirement in updating the DICOM standard is to maintain effective compatibility with previous
editions.
The maintenance process may involve retirement of sections of the DICOM standard.
Retirement does not imply that these features cannot be used. However, the DICOM Standards
Committee will not maintain the documentation of retired features. The reader is referred to earlier
editions of the DICOM standard.
The use of the retired features is discouraged for new implementations, in favour of those alternatives
remaining in the DICOM standard.
0.2.3 Information objects and unique object identification
Many DICOM services involve the exchange of persistent information objects, such as images. An
instance of such an information object may be exchanged across many systems and many organizational
contexts, and over time. While minor changes may be made to the attributes of an instance to facilitate
its handling within a particular organization (e.g. by coercing a Patient ID to the value used in a local
context), the semantic content of an instance does not change.
Each instance is identified by a globally unique object identifier, which persists with the instance across
all exchanges. Changes to the semantic content of an instance are defined to create a new instance,
which is assigned a new globally unique object identifier.
0.2.4 Conformance
Conformance to the DICOM standard is stated in terms of Service-Object Pair (SOP) Classes, which
represent Services (such as Storage using network, media, or web) operating on types of Information
Objects (such as CT or MR images).
SOP Class specifications in the DICOM standard are only changed in a manner that is intended to be
forward and backward compatible for all editions of the DICOM standard. Conformance requirements
vi © ISO 2017 – All rights reserved
---------------------- Page: 12 ----------------------
SIST EN ISO 12052:2018
ISO 12052:2017(E)
and conformance claims are therefore referenced to the identifier of the SOP Class, and never referenced
to an edition of the DICOM standard.
Each implementation is required to provide a Conformance Statement, in accordance with a consistent
pro forma structure, facilitating comparison of products for interoperability.
0.2.5 Consistency of information model
A large number of information objects defined in the DICOM standard follow a common composite
information model with information entities representing Patient, Study, Series, Equipment, Frame of
Reference, and the specific instance data type. This information model is a simplification of the real
world concepts and activities of medical imaging; for acquisition modalities, a Study is approximately
equivalent to an ordered procedure, and a Series is approximately equivalent to a performed data
acquisition protocol element. In other domains, such as Radiotherapy, the Study and Series are less
clearly related to real world entities or activities, but are still required for consistency. This simplified
model is sufficient for the pragmatic needs of managing imaging and related data collected in routine
practice.
New information objects defined in DICOM will typically conform to this existing common information
model, allowing reuse of implementations with minimal changes to support the new objects.

Health informatics — Digital imaging and communication
in medicine (DICOM) including workflow and data
management
1 Scope
This document, within the field of health informatics, addresses the exchange of digital images and
information related to the production and management of those images, between both medical imaging
equipment and systems concerned with the management and communication of that information.
This document facilitates interoperability of medical imaging equipment by specifying:
— for network communications, a set of protocols to be followed by devices claiming conformance to
this document;
— the syntax and semantics of Commands and associated information which can be exchanged using
these protocols;
— for media communication, a set of media storage services to be followed by devices claiming
conformance to this document, as well as a File Format and a medical directory structure to facilitate
access to the images and related information stored on interchange media;
— information that is to be supplied with an implementation for which conformance to this document
is claimed.
This document does not specify:
— the implementation details of any features of the DICOM standard on a device claiming conformance;
— the overall set of features and functions to be expected from a system implemented by integrating
a group of devices each claiming conformance to this document;
— a testing/validation procedure to assess an implementation’s conformance to this document.
This document pertains to the field of medical informatics. Within that field, it addresses the exchange
of digital information between medical imaging equipment and other systems. Because such equipment
may interoperate with other medical devices and information systems, the scope of this document
needs to overlap with other areas of medical informatics. However, this document does not address the
full breadth of this field.
This document has been developed with an emphasis on diagnostic medical imaging as practiced in
radiology, cardiology, pathology, dentistry, ophthalmology and related disciplines, and image-based
therapies such as interventional radiology, radiotherapy and surgery. However, it is also applicable to a
wide range of image and non-image related information exchanged in clinical, research, veterinary, and
other medical environments.
This document facilitates interoperability of systems claiming conformance in a multi-vendor
environment, but does not, by itself, guarantee interoperability.

0 Introduction
Digital Imaging and Communications in Medicine (DICOM) is the standard for the communication and
management of medical imaging information and related data.
0.1 History
With the introduction of computed tomography (CT) followed by other digital diagnostic imaging
modalities in the 1970s, and the increasing use of computers in clinical applications, the American
College of Radiology (ACR) and the National Electrical Manufacturers Association (NEMA) recognized
the emerging need for a standard method for transferring images and associated information between
devices manufactured by various vendors. These devices produce a variety of digital image formats.
The American College of Radiology (ACR) and the National Electrical Manufacturers Association
(NEMA) formed a joint committee in 1983 to develop a standard to:
— promote communication of digital image information, regardless of device manufacturer;
— facilitate the development and expansion of picture archiving and communication systems (PACS)
that can also interface with other systems of hospital information;
— allow the creation of diagnostic information databases that can be interrogated by a wide variety of
devices distributed geographically.
ACRNEMA standards Publication No. 3001985, published in 1985, was designated version 1.0. The
standard was followed by two revisions: No. 1, dated October 1986 and No. 2, dated January 1988.
These standards publications specified a hardware interface, a minimum set of software commands,
and a consistent set of data formats.
ACRNEMA standards Publication No. 3001988, published in 1988, was designated version 2.0. It
included version 1.0, the published revisions, and additional revisions. It also included new material
to provide command support for display devices, to introduce a new hierarchy scheme to identify an
image, and to add data elements for increased specificity when describing an image.
In 1993, ACR-NEMA/Standard 300 was substantially revised and replaced by this document,
designated Digital Imaging and Communications in Medicine (DICOM). It embodies a number of major
enhancements to previous versions of the ACRNEMA standard, as listed below.
— It is applicable to a networked environment. The ACRNEMA standard was applicable in a pointto
point environment only; for operation in a networked environment, a Network Interface Unit (NIU)
was required. DICOM supports operation in a networked environment using the industry standard
networking protocol TCP/IP.
— It is applicable to offline media exchange. The ACR-NEMA standard did not specify a file format
or choice of physical media or logical filesystem. DICOM supports operation in an offline media
environment using industry standard media such as CD-R, DVD-R and USB and common file systems.
— It is a service-oriented protocol, specifying the semantics of commands and associated data, and how
devices claiming conformance to the DICOM standard react to commands and data being exchanged.
Specified services include support for management of the workflow of an imaging department. The
ACR-NEMA standard was confined to the transfer of data with only implicit service requirements.
— It specifies levels of conformance. The ACR-NEMA standard specified a minimum level of conformance.
DICOM explicitly describes how an implementor must structure a Conformance Statement to select
specific options.
In 1995, with the addition of DICOM capabilities for cardiology imaging supported by the American
College of Cardiology, the ACR-NEMA Joint Committee was reorganized as the DICOM standards
Committee, a broad collaboration of stakeholders across all medical imaging specialities.

---------------------- Page: 7 ----------------------
oSIST prEN ISO 12052:2017
ISO/FDIS 12052:2017(E)
0.2.1 Global applicability and localization
DICOM is a world-wide standard that can be used in every locale. It provides mechanisms to handle
data that support cultural requirements, such as different writing systems, character sets, languages,
and structures for addresses and person names. It supports the variety of workflows, processes and
policies used for biomedical imaging in different geographic regions, medical specialities and local
practices.
Localization to meet the requirements of national or local health and workflow policies can be done
without deviating from the DICOM standard. Such localization may include specifying code sets (e.g.
procedure codes) or profiling data element usage (both specifying locally-allowed values, and making
elements that are optional in the DICOM standard mandatory for local use).
Localization and profiling can be specified in a number of mechanisms outside the purview of the
DICOM standard. One such mechanism is Integration Profiles from the Integrating the Healthcare
Enterprise (IHE) organization. It is important that Profiling adhere to the concept of non-contradiction.
A Profile can add requirements but should not contradict DICOM requirements, as that would make it
impossible to comply with both DICOM and the Profile.
0.2.2 Continuous maintenance
The DICOM standard is an evolving standard and it is maintained in accordance with the Procedures of
the DICOM standards Committee. Proposals for enhancements are welcome from all users of the DICOM
standard and may be submitted to the Secretariat. Supplements and corrections to the DICOM standard
are balloted and approved several times a year. When approved as Final Text, each change becomes
official, is published separately, and goes into effect immediately. At intervals, all of the approved Final
Text changes are consolidated and published in an updated edition of the DICOM standard. Once changes
are consolidated into an updated edition of the DICOM standard, the individual change documents are
not maintained; readers are directed to use the consolidated edition of the DICOM standard.
A requirement in updating the DICOM standard is to maintain effective compatibility with previous
editions.
The maintenance process may involve retirement of sections of the DICOM standard.
Retirement does not imply that these features cannot be used. However, the DICOM standards
Committee will not maintain the documentation of retired features. The reader is referred to earlier
editions of the DICOM standard.
The use of the retired features is discouraged for new implementations, in favour of those alternatives
remaining in the DICOM standard.
0.2.3 Information objects and unique object identification
Many DICOM services involve the exchange of persistent information objects, such as images. An
instance of such an information object may be exchanged across many systems and many organizational
contexts, and over time. While minor changes may be made to the attributes of an instance to facilitate
its handling within a particular organization (e.g. by coercing a Patient ID to the value used in a local
context), the semantic content of an instance does not change.
Each instance is identified by a globally unique object identifier, which persists with the instance across
all exchanges. Changes to the semantic content of an instance are defined to create a new instance,
which is assigned a new globally unique object identifier.
0.2.4 Conformance
Conformance to the DICOM standard is stated in terms of ServiceObject Pair (SOP) Classes, which
represent Services (such as Storage using network, media, or web) operating on types of Information
Objects (such as CT or MR images).
SOP Class specifications in the DICOM standard are only changed in a manner that is intended to be
forward and backward compatible for all editions of the DICOM standard. Conformance requirements
vi © ISO 2017 – All rights reserved
---------------------- Page: 8 ----------------------
oSIST prEN ISO 12052:2017
ISO/FDIS 12052:2017(E)
and conformance claims are therefore referenced to the identifier of the SOP Class, and never referenced
to an edition of the DICOM standard.
Each implementation is required to provide a Conformance Statement, in accordance with a consistent
pro forma structure, facilitating comparison of products for interoperability.
0.2.5 Consistency of information model
A large number of information objects defined in the DICOM standard follow a common composite
information model with information entities representing Patient, Study, Series, Equipment, Frame of
Reference, and the specific instance data type. This information model is a simplification of the real
world concepts and activities of medical imaging; for acquisition modalities, a Study is approximately
equivalent to an ordered procedure, and a Series is approximately equivalent to a performed data
acquisition protocol element. In other domains, such as Radiotherapy, the Study and Series are less
clearly related to real world entities or activities, but are still required for consistency. This simplified
model is sufficient for the pragmatic needs of managing imaging and related data collected in routine
practice.
New information objects defined in DICOM will typically conform to this existing common information
model, allowing reuse of implementations with minimal changes to support the new objects.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 12052:2017(E)
Health informatics — Digital imaging and communication
in medicine (DICOM) including workflow and data
management
1 Scope
This document, within the field of health informatics, addresses the exchange of digital images and
information related to the production and management of those images, between both medical imaging
equipment and systems concerned with the management and communication of that information.
This document facilitates interoperability of medical imaging equipment by specifying:
— for network communications, a set of protocols to be followed by devices claiming conformance to
this document;
— the syntax and semantics of Commands and associated information which can be exchanged using
these protocols;
— for media communication, a set of media storage services to be followed by devices claiming
conformance to this document, as well as a File Format and a medical directory structure to facilitate
access to the images and related information stored on interchange media;
— information that is to be supplied with an implementation for which conformance to this document
is claimed.
This document does not specify:
— the implementation details of any features of the DICOM standard on a device claiming conformance;
— the overall set of features and functions to be expected from a system implemented by integrating
a group of devices each claiming conformance to this document;
— a testing/validation procedure to assess an implementation’s conformance to this document.
This document pertains to the field of Medical Informatics. Within that field, it addresses the exchange
of digital information between medical imaging equipment and other systems. Because such equipment
may interoperate with other medical devices and information systems, the scope of this document
needs to overlap with other areas of medical informatics. However, this document does not address the
full breadth of this field.
This document has been developed with an emphasis on diagnostic medical imaging as practiced in
radiology, cardiology, pathology, dentistry, ophthalmology and related disciplines, and image-based
therapies such as interventional radiology, radiotherapy and surgery. However, it is also applicable to a
wide range of image and non-image related information exchanged in clinical, research, veterinary, and
other medical environments.
This document facilitates interoperability of systems claiming conformance in a multi-vendor
environment, but does not, by itself, guarantee interoperability.
