标准摘要
[中文适用范围]： This part of IEC 61675 specifies terminology and test methods for declaring the characteristics of Positron Emission Tomographs. Positron Emission Tomographs detect the ANNIHILATION RADIATION of Positron emitting RADIONUCLIDES by COINCIDENCE DETECTION. [外文原描述]： IEC 61675-1:2022 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61675-1:2022 specifies terminology and test methods for declaring the characteristics of POSITRON EMISSION TOMOGRAPHS. POSITRON EMISSION TOMOGRAPHS detect the ANNIHILATION RADIATION of positron emitting RADIONUCLIDES by COINCIDENCE DETECTION. IEC 61675-1:2022 cancels and replaces the second edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: requirements have been changed or newly created regarding the technical aspects of SPATIAL RESOLUTION, sensitivity measurement, SCATTER FRACTION, COUNT RATE performance, image quality, PET/CT registration accuracy and time-of-flight resolution.
