Non-destructive testing - Radiation methods for computed tomography - Part 3: Operation and interpretation (ISO 15708-3:2017)

ISO 15708-3:2017 presents an outline of the operation of a computed tomography (CT) system and the interpretation of results with the aim of providing the operator with technical information to enable the selection of suitable parameters.
It is applicable to industrial imaging (i.e. non-medical applications) and gives a consistent set of CT performance parameter definitions, including how those performance parameters relate to CT system specifications.
ISO 15708-3:2017 deals with computed axial tomography and excludes other types of tomography such as translational tomography and tomosynthesis.

Zerstörungsfreie Prüfung - Durchstrahlungsverfahren für Computertomografie - Teil 3: Durchführung und Auswertung (ISO 15708-3:2017)

Dieses Dokument bietet einen Überblick über den Betrieb eines Computertomographie (CT )Systems und die Auswertung der Ergebnisse, um dem Anwender technische Informationen zur Auswahl geeigneter Para¬meter zur Verfügung zu stellen.
Es gilt für die industrielle Bildgebung (d. h. nicht medizinische Anwendungen) und bietet einen einheitlichen Satz von Festlegungen zu CT Leistungsparametern, einschließlich der Art des Zusammenhangs dieser Leistungsparameter mit den Spezifikationen des CT Systems.
Dieses Dokument befasst sich mit der axialen Computertomographie und schließt weitere Arten der Tomo-graphie, wie z. B. Translationstomographie und Tomosynthese, aus.

Essais non destructifs - Méthodes par rayonnements pour la tomographie informatisée - Partie 3: Fonctionnement et interprétation (ISO 15708-3:2017)

Le présent document fournit une présentation générale du fonctionnement d'un système de tomographie informatisée (TI) et de l'interprétation des résultats afin de donner à l'utilisateur des informations techniques pour sélectionner les paramètres adaptés.
Il est applicable à l'imagerie industrielle (c'est-à-dire aux applications non médicales) et donne un ensemble cohérent de définitions des paramètres de performance de la TI, y compris la façon dont ces paramètres sont reliés aux spécifications du système TI.
Le présent document traite de la tomographie axiale informatisée et exclut les autres types de tomographie, tels que la tomographie par translation et la tomosynthèse.

Neporušitvene preiskave - Sevalne metode za računalniško tomografijo - 3. del: Delovanje in razlaga (ISO 15708-3:2017)

Standard ISO 15708-3:2017 opisuje delovanje sistema računalniške tomografije (CT) in razlago rezultatov z namenom zagotavljanja tehničnih podatkov uporabniku za omogočanje izbire ustreznih parametrov.
Uporablja se za slikanje v industriji (npr. v nemedicinske namene) in podaja dosleden sklop definicij podatkov delovanja računalniške tomografije, vključno s tem, kako so podatki delovanja povezani s specifikacijami sistema računalniške tomografije.
Standard ISO 15708-3:2017 obravnava računalniško aksialno tomografijo in izključuje druge vrste tomografij, kot so translacijska tomografija in tomosinteza.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for
