A prototype of proton Computed Tomography (pCT) system for hadron-therapy has been manufactured and tested in a 175 MeV proton beam with a non-homogeneous phantom designed to simulate high- contrast material. BI-SART reconstruction algorithms have been implemented with GPU parallelism, taking into account of most likely paths of protons in matter. Reconstructed tomography images with density resolutions r.m.s. down to 1% and spatial resolutions o 1 mm, achieved within processing times of 15 ′ for a 512 512 pixels image prove that this technique will be bene fi cial if used instead of X-CT in hadron-therapy.
