Abstract

We are developing a dual-headed small-animal SPECT system using double-sided strip HPGe detectors. HPGe provides superior energy resolution (approximately 1 % FWHM at 140 keV), which allows for good scatter rejection and facilitates dual- or multi-isotope imaging. Reconstructed images in our first prototype small-animal SPECT system exhibited artifacts, which we attributed to mis-positioning of events near the strip edges. To study the detector response and acqnire data to facilitate the development of methods to recover multi-strip events, we have scanned a detector with a focused beam (approximately 25\mathrm {x} 25 {\mu } \mathrm {m} 2 @ 131 keV)()
