利用直径为3mm的雪崩光电二极管观察9.5/spl倍/4/spl倍/ 4mm /sup 3/ LSO晶体，进行了高分辨率正电子发射层析成像的可行性研究。使用Na/sup 22/光源，作者确定了2.3/spl + usmn/0.1 mm的空间分辨率，约15%的能量分辨率和2.6 nsec的时间分辨率。给出了大规模测试和层析成像的可能配置。<<ETX>>
A feasibility study for a high resolution positron emission tomograph, based on 9.5/spl times/4/spl times/4 mm/sup 3/ LSO crystals viewed by 3 mm diameter avalanche photodiodes, has been carried out. Using a Na/sup 22/ source the authors determined a spatial resolution of 2.3/spl plusmn/0.1 mm, an energy resolution around 15% and a time resolution of 2.6 nsec. Possible configurations for larger scale tests and a tomograph are given.<<ETX>>
