Paper Abstract

The presented here abstract presents shortly an iterative approach to reconstruction problem for positron emission tomography (PET) imaging technique. The conception proposed here is based on a continuous-to-continuous data model, and a reconstruction problem is formulated as a shift-invariant system. The reconstruction problem is formulated taking into consideration the statistical properties of signals obtained by PET scanner. Computer simulations have been performed which prove that the reconstruction algorithm described here significantly overperforms EM-ML method based on discrete-to discrete data model on the quality of the images obtained.
