Research on the detection of SPECT quality control / 中国医学装备

ABSTRACT

Objective:To explore the SPECT detection method of quality control in detection of main performance index. Methods: according to the 2007 edition of SPECT performance measurementof the NEMA (the United States Electrical Manufacturers Association) standard, and the corresponding model of intrinsic spatial resolution, intrinsic spatial non-linearity, intrinsic non-uniformity, characteristic count rate, system planar sensitivity, system spatial resolution, fault spatial resolution and other indicators. Results: after quality control testing, have deviation more index hospitals SPECT results. Conclusion: the hospital should detect quality control as far as possible in nuclear medicine and nuclear medicine imaging equipment, ensure the normal operation of equipment, and improve the quality of image.
