DEVELOPMENT OF A MONTE CARLO SIMULATION TOOL FOR LIGHT TRANSPORT INSIDE SCINTILLATION CRYSTALSYang, Xin 10 1900 (has links)
<p>The scintillation crystal is a critical component in positron emission tomography (PET) systems. It impacts a number of PET system performance parameters, including spatial, energy, and time resolution. Our goal is to develop a new simulation tool to achieve improved accuracy by addressing several limitations in the existing packages, including more advanced surface treatments, temporal dependency of photon arrival, and rigorous experimental validations. The comparison of preliminary Monte Carlo simulation results and analytical calculations for specular reflection suggest that the simulation model is working well. The time-resolved light output was studied for various crystal surface treatment configurations. The measured energy resolutions are in the range of approximately 10% to 15%, which are in good agreement with published literatures. Based on the simulation and experimental results, the polished surface treatment, used together with an external specular reflector, is able to provide the best energy resolution and timing resolution for a LYSO (3x3x20 mm<sup>3</sup>) and SiPM assembly we tested. The AsCut surface with external diffusion reflector is not desired due to its inferior energy and timing resolutions. The direction and recommendation of improvements of simulation regarding surface models and wavelength dependency, as well as potential optimization of experiment such as timing pickoff methods, are discussed.</p> / Master of Science (MSc)

Performance optimization of a PET insert for simultaneous breast PET/MR imagingLiang, Yicheng 10 1900 (has links)
<p>Our group aims to develop a dedicated PET/MR system for breast cancer imaging. In order to evaluate and optimize the performance of the PET component, Monte Carlo simulation was made to help us choose the configuration parameters for hardware design. A resolution modeling method was also proposed and implemented on the GPU device to not only improve the spatial resolution of the reconstructed images but also accelerate the reconstruction speed. The PET component is configured with a ring shape composed of LYSO+SiPM detectors. Such design is compatible to MRI, and feasible for time of flight PET. Several aspects are included to be investigated in the simulation which are geometry configuration, counting performance and image quality. From the simulation result, the system configured using 2x2x20mm3 LYSO crystal with two DOI layers and 3 detector rings results in 6.2% photon sensitivity. The Noise equivalent count rate is improved with better time resolution, the peak NEC is found to be 7886 cps with 250 ps time resolution. The system is able to achieve 2.0 mm spatial resolution which is found to be more uniform with the addition of DOI layers. With the help of TOF, the lesion is visualizable with shorter scan time than the non-TOF system. The resolution modeling method is based on the coincidence detection response function modeling and multiray projection. It is found to improve the spatial resolution uniformity and contrast recovery. At the same time it reduces the position offset and background noise. The speed and accuracy improvement for this model is also discussed.</p> / Master of Science (MSc)
