Description

Proton Computed Tomography (pCT) is a new imaging method with a potential for increasing accuracy of treatment planning and patient positioning in hadron therapy. A pCT system based on a silicon tracker and a YAG:Ce calorimeter has been developed within the PRIMA/RDH/IRPT INFN CSN5 collaboration. The pCT prototype has been tested under 62MeV and 180MeV proton beams at respectively Laboratori Nazionali del Sud ( Catania, Italy ) and Svedberg Laboratory (Uppsala, Sweden). Data analysis has been performed using algebraic iterative reconstruction algorithms. In this talk, functional characteristics of the pCT system under test beam will be discussed; images of non homogeneous phantoms resulting from the pCT reconstruction will be shown and main results in term of spatial and density resolutions will be reviewed.
