研究了一种正电子发射乳房X线机的性能特点。该代谢乳腺成像系统的空间分辨率为2.8 mm半高全宽，符合分辨时间为12纳秒半高宽，绝对效率为3%。在信号与背景活度比为6：1的体模中，扫描时间为5分钟，可分辨出直径为16 mm的热点。
Performance characteristics of a positron emission mammographic (PEM) instrument were studied. This dedicated metabolic breast imaging system has spatial resolution of 2.8-mm full width at half maximum (FWHM), coincidence resolving time of 12-nsec FWHM, and absolute efficiency of 3%. Hot spots with diameter of 16 mm in a phantom with signal-to-background activity ratio of 6:1 were distinguishable with a scanning time of 5 minutes.
