Dependence of image quality on the type of filter and the "cut off" value in SPECT reconstruction using filtered backprojection (FBP) in examinations with the use of Ga-67

Introduction. Although the whole body scan is the standard method of examination, yet the use of SPECT may provide additional information. Because a number of different filters may be used with a number of different "cut-off" values we have performed a study in order to pick their optimal combination.
