| Abstract: | Objective:To evaluate SPECT planar imaging performances and conduct the acceptance test to provide basis for patient safety and image quality in clinical practice. Methods:SPECT planar imaging performances intrinsic spatial resolution, intrinsic spatial linearity, intrinsic energy resolution, intrinsic uniformity, maximum count rate and system planar sensitivity were tested for two types of SPECT devices. Results:There was a little difference between the performances of two types of SPECT devices. The intri... |
