Description
Proton Computed Tomography directly measures the proton stopping power in a patient to improve proton radiotherapy treatment plans. Conventionally the energy measurement in proton CT is performed via scintillators or range trackers which are limited to at most a few protons per readout cycle. We present here a proton CT device which utilises silicon strip trackers oriented at non orthogonal angles to improve rate capabilities coupled with a CMOS MAPS which integrated the energy deposited by multiple protons per pixel. We will describe the devices used, the reconstruction method for achieving a proton CT, and present proof of principle results obtained using the University of Birmingham MC40 cyclotron.
