Medical imaging applicability study of silicon pixel detectors with PSI46dig ROC

Abstract

The aim of the Multispectral Photon Counting for Medical Imaging and Beam Characterization (MPMIB) project is to develop a next-generation medical imaging detecting system capable of multispectral imaging. One of the ways is to employ a direct detection system based on photon counting with silicon pixel sensors, using readout electronics developed for high-energy physics experiments. This thesis contains an analysis of experiments performed at the Nuclear Safety Authority of Finland (STUK). The measuring campaign included the evaluation of thin silicon pixel detectors with X-rays and beam dosimetry in the water of a Co-60 gamma-ray source. These activities are related to the MPMIB project objectives and are supplying unique experimental data.
