Abstract Introduction: The purpose of this study was to define an optimal parameter for the
tomographic reconstruction procedure in routine single photon emission tomography
(SPECT) studies. In this study Hoffman Brain Phantom is modified in such a way that only
software capability is evaluated. The phantom is composed of several independent slice that
can be imaged individually (planar) or in 3-D composition (SPECT). Method and Materials:
Planar image of the slices were imaged separately. The tomographic image was ..
