Effect of unconventional filters on uniformity, sensitivity and linearity of an imaging system in SPECT

Effect of unconventional filters on uniformity, sensitivity and linearity of an imaging system in SPECT

The prime objective of the SPECT imaging is to provide the best possible diagnostic service to the patient's. For achieving this. It is vital to tset the performance parameters of the imaging system. Such as, spatial resolution, centre of rotation, uniformity, linearity and sensitivity. In this...
