In this paper a first proprietary apparatus to undergo proton computed tomography (pCT), manufactured in the framework of the PRIMA (PRoton IMAging) project (INFN-CSN5), will be described. The system, able to carry out single projections at different rotating angles of the phantom, is characterized by a field of view of about 5x5cm2 and an acquisition time of the order of 10s (10 kHz, 105 events). The complete system has been characterized with 62MeV protons at Laboratori Nazionali del Sud (LNS-INFN) and first radiographic and tomographic images have been reconstructed: main results will be shown and discussed. The design and manufacture of a novel prototype of pCT system for pre-clinical applications is now under development. The system is characterized by: (a) a larger active area and (b) an acquisition system able to store data from a whole tomographic image without dead times. All details will be discussed.
