Proton Computed Tomography (pCT) can improve the accuracy of both patient positioning and dose calculation in proton therapy, enabling to accurately reconstruct the electron density distribution of irradiated tissues. A pCT prototype, equipped with a silicon tracker and a YAG:Ce calorimeter, has been manufactured by an Italian collaboration. First tests under proton beam allowed obtaining good quality tomographic images of a non-homogeneous phantom. Manufacturing of a new large area system with real-time data acquisition is under way.

“…For these reasons the YAG:Ce is indicated for application with high energy particle, high count rate, good energy resolution and minimal amount of space. The YAG:Ce scintillator proprieties were investigated in [1] and a calorimeter with four crystals was manufactured for application in the proton Computed Tomography (pCT) apparatus described in [3][4][5][6][7][8][9]. The use of protons for tomographic images can represent an improvement in the quality of a proton therapy treatment because of the possibility of having on-line patient positioning and more accurate dose calculation, measuring directly the protons stopping power map.…”

“…The use of protons for tomographic images can represent an improvement in the quality of a proton therapy treatment because of the possibility of having on-line patient positioning and more accurate dose calculation, measuring directly the protons stopping power map. In order to meet the pCT requirements the calorimeter has to stop up to 200MeV protons and to sustain 1MHz particle rate [3][4][5][6][7][8][9]. For these purposes four optically separated crystals, each with a 3x3cm 2 active area, long 10 cm and assembled in the same housing, have been manufactured.…”

A YAG:Ce calorimeter with a 6x6 cm 2 active area, long 10 cm has been manufactured in order to stop up to 200 MeV protons and to sustain 1MHz particle rate. It consists of four optically separated crystals assembled in the same housing. The YAG:Ce scintillator is promising for charged particle detection applications where high-count rate, good energy resolution and compact photodiode readout, not influenced by magnetic fields, are of importance. The YAG:Ce calorimeter has been characterized with proton beams up to 175MeV a The Svedberg Laboratory (TSL), Uppsala Sweden. Results obtained are shown and discussed.

“…A first pCT prototype, based on a silicon tracker and a YAG:Ce calorimeter with a 5x5 cm 2 active area and a 10 kHz data rate, has been developed within the PRIMA collaboration [8][9][10][11]. First results on tomographic reconstruction show that a spatial resolution of the order of 1 mm can be achieved [12][13][14].…”

Abstract-Proton Computed Tomography (pCT) is an imaging method under investigation with the aim to improve the accuracy of treatment planning and patient positioning in hadron therapy. A pCT system should be capable to measure tissue electron density with an accuracy better than 1% and with a spatial resolution better than 1mm. A first apparatus based on a silicon tracker and a YAG:Ce crystal calorimeter, with a 5x5 cm 2 active area, has been already developed by the authors in the framework of the PRIMA (Proton Imaging) collaboration and tested with proton beams with promising results. A second prototype with larger area (5x20 cm 2 ) and improved data acquisition system is being designed. The details about this new prototype will be presented in this work.
