Purpose : We present an approach for concurrent reconstruction of respiratory motion compensated abdominal DCE-MRI and PET data in an integrated PET/MR scanner. The MR and PET reconstructions share the same motion vector fields (MVFs) derived from...

Abstract : Positron emission tomography (PET) in medicine exploits the properties of positron-emitting unstable nuclei. The pairs of γ-rays emitted after annihilation are revealed by coincidence detectors and stored as projections in a sinogram. It is...

Scipioni M., Santarelli M. F., Positano V., Landini L. "The Influence of Noise in Dynamic PET Direct Reconstruction". XIV Mediterranean Conf. on Medical and Biological Engineering and Computing. (pp. 308–313). Springer International Publishing. 2016

Abstract In the present work a study is carried out in order to assess the efficiency of the direct reconstruction algorithms on noisy dynamic PET data. The study is performed via Monte Carlo simulations of a uniform cylindrical phantom whose emission...
