Abstract

We realized a prototype of a monitoring system for proton therapy based on the technique of positron emission tomography. For the first time to our knowledge, we used the Plug&Imaging (P&I)Multi Voltage Threshold (MVT) technology in this application. The sensing system includes LYSO/silicon photomultiplier (SiPM) detection elements, fast digital multi voltage threshold (MVT) readout electronics and dedicated image reconstruction algorithms. In this paper we present a new set of data collected with a water phantom and we further demonstrate that the P&I sensor system can be operated in the in-beam beamon experimental conditions of the proton therapy room, reaching a maximal count rate of 5.2 Mcps.
