Gamma Ray Imaging of Small Animals Using Position-Sensitive Photomultiplier Tubes

چکیده
This thesis is an interdisciplinary investigation of small animals consisting of two parts. First, a comparison of NaI(Tl) and CsI(Tl) pixilated scintillating crystals will be presented based on results of resolution tests performed using 5 " diameter Hamamatsu 5800 PSPMTs. Second, application of the gamma ray detectors will be assessed using a biological model. The biological model chosen to analyze is the efficacy of potassium iodide as a blocking agent to the uptake of radioiodine by the thyroid. The blocking dose of potassium iodide is tested and the implications discussed.

Comparative assessment of the accuracy of maximum likelihood and correlated signal enhancement algorithm positioning methods in gamma camera with large square photomultiplier tubes
Introduction: The gamma cameras, based on scintillation crystal followed by an array of photomultiplier tubes (PMTs), play a crucial role in nuclear medicine. The use of square PMTs provides the minimum dead zones in the camera. The camera with square PMTs also reduces the number of PMTs relative to the detection area. Introduction of a positioning algorithm to improve the spat...

We are investigating the concept of utilizing a small gamma ray scintillation camera to help identify and localize malignant breast tumors after a suspicious finding in a mammogram. We are exploring two different photodetector technologies for a small prototype camera development. The first uses a position sensitive photomultiplier (PSPMT) as the photodetector, the second, an array of silicon P...
