Magnetic resonance equipment for medical imaging - Part 2: Classification criteria for pulse sequences (IEC 62464-2:2010)

This International Standard specifies the description of PULSE SEQUENCES of MAGNETIC RESONANCE imaging. NOTE The classification in this standard is suitable for: - tender texts; - image annotation; - protocol definition; - technical publications. This International Standard does not apply to MAGNETIC RESONANCE spectroscopy. The classification does not focus on image contrast (T1, T2, proton density), as this is defined by PULSE SEQUENCE parameters (e.g. repetition time, echo time) and is not a property of the PULSE SEQUENCE alone. The PULSE SEQUENCE classification does not specify the K-SPACE acquisition scheme, reconstruction algorithm or post-processing.

Appareils à résonance magnétique utilisés pour l'imagerie médicale - Partie 2: Critères de classification pour les séquences d'impulsions (CEI 62464-2:2010)

La CEI 62464-2:2010 spécifie la description des sequences d'impulsions de l'imagerie par resonance magnetique. La classification utilisée dans la présente norme convient pour:  - les contenus d'appels d'offres;  - les annotations d'images;  - les définitions de protocoles;  - les publications techniques.  La CEI 62464-2:2010 ne s'applique pas à la spectroscopie par résonance magnétique. La classification ne se concentre pas sur le contraste de l'image (T1, T2, densité protonique), comme ceci est défini par les paramètres de sequences d'impulsions (par exemple temps de répétition, temps d'écho), et n'est pas une propriété de la sequence d'impulsions uniquement. La classification des séquences d'impulsions ne spécifie pas le schéma d'acquisition, l'algorithme de reconstruction ou le post-traitement de l'espace k.

Oprema za magnetno resonanco za medicinsko slikanje - 2. del: Klasifikacijska merila za impulzna zaporedja (IEC 62464-2:2010)

Ta mednarodni standard določa opis IMPULZNIH ZAPOREDIJ pri slikanju z MAGNETNO RESONANCO. OPOMBA Klasifikacija v tem standardu je primerna za: – besedila v javnih razpisih, – označevanje slik, – opredelitev protokolov, – tehnične publikacije. Ta mednarodni standard ne velja za MAGNETNORESONANČNO spektroskopijo. Klasifikacija se ne osredotoča na kontrast slike (T1, T2, protonska gostota), ker to opredeljujejo parametri IMPULZNEGA ZAPOREDJA (npr. hitrost ponavljanja zaporedja, čas spinskega odmeva), in ni lastnost samega IMPULZNEGA ZAPOREDJA. Klasifikacija IMPULZNIH ZAPOREDIJ ne določa sheme K-PROSTORA, rekonstrukcijskega algoritma ali naknadne obdelave.

MAGNETIC RESONANCE EQUIPMENT FOR MEDICAL IMAGING –

Part 2: Classification criteria for pulse sequences


FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62464-2 has been prepared by subcommittee 62B: Diagnostic
imaging equipment, of IEC technical committee 62: Electrical equipment in medical practice.
The text of this standard is based on the following documents:
