Abstract

PET measurements of tracers with a lower dose rate or short radioactive half life sutTer from extremely low SNRs. In these cases standard reconstmction methods (OSEM, EM, filtered backprojection) deliver unsatisfactory and noisy results. Here, we propose to introduce nonlinear variational methods into the reconstruction process to make an efficient use of a-priori information and to attain improved imaging results. We illustrate our technique by evaluating cardiac H₂¹⁵⁰ measurements. The general approach can also be used for other specific goals allowing to incorporate a-priori information about the solution with Poisson distributed data.
