摘要
Abstract
Objective To strictly implement the stability tests of Positron Emission Tomography Computed Tomography (PET/CT) so as to ensure the secure and stable operation of PET/CT equipment, lower the failure rate, prolong the service span and reduce the maintenance costs of PET/CT equipment. Methods According to the test phantoms and methods in NEMA NU 2-2001, the stability test of PET/CT was explored in this paper from multiple aspects including the detector working state, spatial resolution testing, sensitivity testing, SUV calibration and PET/CT image fusion accuracy testing.Results During the process of PET/CT stability test, the unqualiifed item was timely corrected and the failure rate was reduced so as to guarantee the quality of images.Conclusion The stability test of PET/CT could ensure the image quality and reduce the failure rate.关键词
