The SPECT system for image diagnosis in nuclear medicine is as important as X-ray CT in diagnostic radiology and, therefore, this is now widely used in daily practices. However as far as the spatial resolution and the sensitivity are concerned, the SPECT system is apparently inferior to the PET system. In this study we evaluated the influence of various hardware systems over the quality of the image obtained through SPECT system. This includes the arrangement of scintillation detectors, designing of special collimators, development of various methods for data acquisition, etc. In conclusion, we can say that the improvement of hardware systems, which are developed by the makers and are proposed by the users as well, will promote a further improvement of the SPECT image quality.
