Performance evaluation in three geometric detection arrangement for Clinical PET:Simulation study

Considering the human cross section is not exactly a circle and the fact that sensitivity and spatial resolution of PET images formed in coincidence may show better values with reduction of the distance between the coincident detectors three different detection geometries of a PET system have been simulated: one circular and two elliptical. The performance evaluation was done by system parameters: sensitivity, resolution and the Noise Equivalent...
