The applicability of NEMA NU1-2007 for the performance testing of SPECT based on CZT detector / 中国医学装备

ABSTRACT

Objective: To provide reference for the performance testing of single photon emission computed tomography (SPECT) based on CZT detector by correct applying NEMA NU1-2007 that established by NEMA. Methods: When the performance of SPECT based on CZT detector was tested, the CZT detector should be distinguished from single crystal detector. And the items of performance testing of CZT detector that was not suitable for NEMA NU1-2007 standard were discussed and explored. Result: The experiment items which was not suitable for NEMA NU1-2007 standard were grasped, and the research provided the relative analysis of reason and method of disposition. Conclusion: The performance testing of SPECT based on CZT detector could not completely be implemented according to the standard of NEMA NU1-2007. Besides, manufacturer need know which testing items were inapplicable and their reasons.
