1. McDonald, Benjamin Seth. Development of the SiliSPECT Small-Animal Imager.

Degree: PhD, Physics, 2010, Vanderbilt University

SiliSPECT, a multi-pinhole, multi-detector SPECT system, was designed to image targeted regions of rodents at sub-300 micron resolution with stationary data acquisition. High spatial resolution is achieved with thick silicon double-sided strip detectors (DSSDs) and 250 micron pinhole apertures. Each of the two camera heads contain two stacked DSSDs, which collect four multi-pinhole projection images simultaneously, enhancing the total detection efficiency and permitting reconstruction based on the synthetic collimator method. The DSSDs were evaluated for imaging low-energy photons, such as the emissions from iodine-125. Trigger uniformity was improved with an iterative trim adjustment algorithm. Detection efficiency, dead time, charge-sharing, and other detector characteristics were measured. The system sensitivity, resolution, multiplexing and magnification of the full system were assessed. A calibration method was implemented to estimate the geometrical parameters of the system. SiliSPECT was fully characterized and readied for tomographic imaging studies. Advisors/Committee Members: M. Shane Hutson (committee member), Will E. Johns (committee member), Thomas E. Yankeelov (committee member), John C. Gore (committee member), Todd E. Peterson (chair).
