-
摘要: 2001版"PET性能测量"的NEMA(美国电器制造商协会)标准是对1994年版本NEMA标准的修订,使之适合于各类PET(正电子发射体层显像)仪的质量保证和验收测量。内容主要包括以下几个部分:(1)定义、符号和参考出版物;(2)总论;(3)空间分辨率;(4)散射因子、计数丢失和随机符合测量;(5)灵敏度;(6)精确性:计数丢失和随机符合校正;(7)图像质量、衰减和散射校正精确性。Abstract: This paper is concerning on the NEMA Standard Publication NU2-2001of Performance Measure-ments of Positron Emission Tomographs,which is the revised edition of the NEMA Standard Publication NU2-1994.Seven primary sections are included,such as:definitions,symbols and referenced publications;general;spatial resolution;scatter fraction,count losses and randoms measurement;sensitivity;accuracy:corrections for count losses and randoms;image quality,accuracy of attenuation and scatter corrections.
