IEC 61675-1:2013 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. No test has been specified to characterize the uniformity of reconstructed images, because all methods known so far will mostly reflect the noise in the image. This second edition replaces the first edition of IEC 61675-1, published in 1998. This edition constitutes a technical revision. Requirements have been changed regarding the following technical aspects:
- spatial resolution;
- sensitivity measurement;
- scatter fraction;
- count rate performance;
- and image quality. Keywords: imaging, medical device
