Proton CT with Gridpix detectors

Statement of Purpose

The aim is to make a prototype detector system that can function in two ways. Firstly, it should be able to monitor the proton beam position during a therapy session. Secondly, it can be used to image the patient with protons and these images can be overlaid on the existing X-ray CT data to provide the best possible data to calculate the required beam energy for the irradiation procedure.

Scope

The work that needs to be done is to build up the detector system first at Nikhef and test its capabilities with cosmic rays. When the system is operational, the equipment will be shipped to KVI. There we will build up the same set-up step-by-step to verify the functionality of each detector part in-situ. When the system is operational we will test the proton tomography capabilities with phantoms and compare this to GEANT4 simulations and existing X-ray CT data. Also we will determine the effect the gaseous detector Gridpix detector has on the passing proton beam in case of the application of this detector as a beam monitor.

Methodology

Here at Nikhef the supervision will be conducted mainly by the supervisor and PhD-students familiar with Gridpix detector systems. At KVI prof. dr. Sytze Brandenburg will provide the necessary time at the proton beam line and specifically also the part on proton beam tomography.
