Abstract
An experimental investigation into the feasibility of imaging multiple medical radioisotopes with the ProSPECTus Compton camera is presented. The aim of the project is to develop a Compton imaging system configured with segmented solid state detectors, for the purpose of alleviating the limitations of conventional Single Photon Emission Computed Tomography (SPECT) systems. The ProSPECTus system consists of a Si(Li) and HPGe planar detector housed in a magnetic field compatible custom made cryostat. The investigation presented in this thesis has been undertaken with a prototype ProSPECTus system, which consists of Si(Li) and HPGe planar detectors housed in separate cryostats. Analysis of the results attained from investigations into the optimum coincidence window, noise thresholds and image reconstruction techniques as part of this thesis are to be used to inform future developments and measurements. The work presented focuses on an investigation of simultaneous data acquisition with the medical radioisotopes 99mTc and 123I, which emit gammarays with energies of 141 keV and 159 keV, respectively. The experimental methodology of defining parameters for timing and noise thresholds is described along with system ... (continues)
