Abstract:
Objective To investigate the quality control and quality assurance of the SPECT/CT system.Methods The energy peak,energy resolution capacity and the intrinsic uniformity of the device's detector were regularly examined, and the quality control was performed. Results The daily hardware maintain could reduce the rate of system's trouble. The device's energy peak,energy resolution capacity were consistent during half year's observation period. The two detector's intrinsic uniformity were better after calibration than before. [ detector Ⅰ: ( 2.71 ± 0.28 ) vs (2.37±0.11)(t=2.489,P<0. 05);detector Ⅱ:(2.68 ±0.12)vs(2.38 ±0. 19)(t =6.421,P <0.01) ] .Conclusion Regular quality control and maintain could keep the function stabilization,enhance the availability rate of the SPECT/CT system.
