It’s also much more affordable, with the average camera costing between $400,000 and $600,000. Then, we take that data and process it using a back projection algorithm to create transaxial slices (think of a ct) It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy), but is able to provide true 3d information.

Three gamma rays emitted in the case of a spect scan. The spect system is more sensitive than the ordinary gamma camera, but the cost of purchase and maintenance is relatively high [1].therefore, small volume portable gamma cameras will have high. Usually one, two or three detectors or heads, are slowly rotated around the patient's. The main difference between spect and pet scans is the type of radiotracers used.
