SPECT验收测试与质量控制

简要地阐述了SPECT特别是目前国内最新引进的带数字化的双探头以及螺旋扫描机架的SPECT的安装收测试，从系统的物理，机械到NEMA标准的性能测试及合同所规定的计算软硬件等几方面分别加以阐述，还对系统的空间分辨率，能量分辨率，空间线性，均匀性，旋转中心等几个方面对SPECT的质量控制也做了简要介绍。

Acceptance Check and Quality Control of SPECT

This paper explains the testing of SPECT,especially the new SPECT with double digital detector and spiral scanning frames that has been introduced to China recently,in the acceptance check,proceeding from the physical functions of the system to its mechanical functions, to the NEMA standard functions,and then to the computer hardware specified in the contract.A brief introduction is also given of the quality control of SPECT in terms of its spatial resolution,energy resolution,spatial linearity,sensitivity, and center of rotation.
