Non-destructive testing - Radiation methods for computed tomography - Part 4: Qualification (ISO 15708-4:2017)
ISO 15708-4:2017 specifies guidelines for the qualification of the performance of a CT system with respect to various inspection tasks.
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 15708-4:2017 deals with computed axial tomography and excludes other types of tomography such as translational tomography and tomosynthesis.
Zerstörungsfreie Prüfung - Durchstrahlungsverfahren für Computertomografie - Teil 4: Qualifizierung (ISO 15708-4:2017)
Dieses Dokument legt Leitlinien für die Qualifizierung des Leistungsverhaltens eines CT-Systems unter Beachtung verschiedener Prüfaufgaben fest.
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 Tomographie, wie z. B. Translationstomographie und Tomosynthese, aus.
Essais non destructifs - Méthodes par rayonnements pour la tomographie informatisée - Part 4: Qualification (ISO 15708-4:2017)
Le présent document décrit des lignes directrices pour qualifier la performance d'un système TI par rapport à différentes tâches d'examen.
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 - 4. del: Usposobljenost (ISO 15708-4:2017)
Standard ISO 15708-4:2017 določa smernice za oceno usposobljenosti delovanja sistema računalniške tomografije glede na različne kontrolne naloge.
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 15708-4:2017 obravnava računalniško aksialno tomografijo in izključuje druge vrste tomografij, kot so translacijska tomografija in tomosinteza.
