Though the use of instruments for SPECT imaging is prevailing, the SPECT images from the several instruments appears many difference in quality respectively. For the purpose of studying the cause of different image quality between several instruments, SPECT images of the same phantom were acquired and processed using 6 instruments in 5 institutes to compare. Up to now the quality of SPECT images was fundamentally dependent on the hardware, but factors of software, such as reconstruction algorithms and determinations of several parameters seemed to have more important effect upon the image quality. The adoption of appropriate processing method after minimizing the imaging deterioration due to the hardware would make the difference of image quality minimum, and could make the standardization of SPECT imaging possible.
