This paper presents a class of image reconstruction algorithms based on Amari's ฮฑ-divergence for position emission tomography. The ฮฑ-divergence is actually a family of divergences indexed by ฮฑโ(-โ, +โ) that can measure discrepancy between two distributions. We consider it to model the discrepancy be
