Quality control for different gamma cameras

ABSTRACT

Single photon emission computed tomography [SPECT] has become a routine part of virtually every nuclear medicine department up to six fold increase in image, contrast can be obtained with SPECT by removing out of plane information[1]. SPECT quality control has always been a prominent and essential feature, because the diagnostic utility depends on the fidelity of imaging [2,3,4]. Quality control tests were performed on two SPECT systems where uniformity, resolution linearity and center of rotation tests were done. A densitometric study for the intrinsic uniformity flood films was performed. The study revealed that one system [camera A] had a better uniformity resolution linearity and a similar center of rotation results:
