标准摘要
[中文适用范围]： IEC 61675 的这一部分规定了用于声明正电子发射断层扫描仪特性的术语和测试方法。正电子发射断层扫描仪通过重合检测来检测正电子发射放射性核素的湮没辐射。尚未指定任何测试来表征重建图像的均匀性@，因为迄今为止已知的所有方法都将主要反映图像中的噪声。 [外文原描述]： 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
