Non-destructive testing - Radiation methods for computed tomography - Part 3: Operation and interpretation (ISO 15708-3:2025)
This document provides an overview of the operation of a computed tomography (CT) system. This document specifies steps for interpretation of CT results with the aim of providing the operator with technical information to enable selection of suitable parameters.
This document is applicable to industrial imaging (i.e. non-medical applications) and specifies a consistent set of definitions of CT performance parameters, including how these performance parameters relate to CT system specifications.
This document is applicable to computed axial tomography.
This document does not apply to other types of tomography such as translational tomography and tomosynthesis.
Zerstörungsfreie Prüfung - Durchstrahlungsverfahren für Computertomographie - Teil 3: Durchführung und Auswertung (ISO 15708-3:2025)
Dieses Dokument enthält einen Überblick über den Betrieb eines Computertomographie (CT )Systems. In diesem Dokument werden Schritte zur Interpretation von CT-Ergebnissen festgelegt, um dem Anwender technische Informationen für die Auswahl geeigneter Parameter zur Verfügung zu stellen.
Dieses Dokument gilt für die industrielle Bildgebung (d. h. nicht medizinische Anwendungen) und legt eine Reihe einheitlicher Definitionen von CT Leistungsparametern fest sowie deren Zusammenhang mit den Spezifikationen des CT Systems.
Dieses Dokument ist anwendbar für die axiale Computertomographie.
Dieses Dokument ist nicht anwendbar für weitere Arten der Tomographie, wie z. B. Translationstomographie und Tomosynthese.
Essais non destructifs - Méthodes par rayonnements pour la tomographie informatisée - Partie 3: Fonctionnement et interprétation (ISO 15708-3:2025)
Le présent document fournit une vue d’ensemble du fonctionnement d’un système de tomographie informatisée (TI). Il spécifie les étapes permettant d’interpréter les résultats de la TI afin de donner à l’utilisateur des informations techniques pour sélectionner les paramètres adaptés.
Le présent document est applicable à l’imagerie industrielle (c’est-à-dire aux applications non médicales) et spécifie un ensemble cohérent de définitions des paramètres de performance de la TI, y compris la relation entre ces paramètres de performance et les spécifications du système TI.
Le présent document est applicable à la tomographie axiale informatisée.
Le présent document ne s’applique pas aux autres types de tomographie, tels que la tomographie par translation et la tomosynthèse.
