Physical factors affecting quantitative measurements using camera-based single photon emission computed tomography (SPECT)


Journal Article (Academic article)

Describes some physical factors that affect the measurement process of single photon emission computed tomography (SPECT) based on scintillation cameras. Using a rotating camera SPECT system the r.m.s. noise level in attenuation-corrected images of a uniform cylindrical source was found to agree with theoretical predictions. The volumes of plastic spherical sources within a cylindrical volume were computed, and agreed with measured values. SPECT measured radionuclide concentrations over the large 0.01-1.0 μC; ml-1, but compensations for system spatial resolution and scattered gamma photons were required when comparing values for differently shaped sources
