| description | The performance of a scintillation-camera system is assessed to assure the acquisition
of diagnostically reliable images. Decisions-making data to determine acceptability of
camera performance are acquired when some parameters are tested. So, in this study the
sensitivity, uniformity and system spatial resolution parameters are tested by using physical
filters, aluminum 0.2 mm and aluminum 0.3 mm. The Tc-99m is used as a source. Two
collimator are used which are low energy parallel-hole collimators, i.e. low energy high
resolution (L.E.H.R) and low energy general purpose (L.E.G.P.). The reason for this choice
was that these collimators are the most commonly used for clinical studies in nuclear
medicine departments. For data acquisition, the method utilizes a photopeak energy window
ranging 126 keV-154 keV ofTc-99m spectrum with 128 x 128 matrix size were used for all
tests. From sensitivity, uniformity, and spatial resolution results material filtered data shows
an improvement. |
