Abstract:
The high-resolution breast camera under development for this project consists of many detector modules formed by coupling pairs of high resolution scintillation crystal arrays to position sensitive avalanche photodiodes (PSAPDs). We finalized the design of these modules. We operated 16 of these simultaneously and no electrical shorts were observed. Software was written to analyze performance of many of these modules. We achieve an average energy resolution of 10%. In addition, progress has been made on constructing a block setup to analyze performance in terms of imaging capabilities. Redesign of the electronics was required to decrease noise in the setup. Currently tests are under way with the updated electronics. Reportable outcomes include 3 peer reviewed publications, one submitted, 4 abstracts submitted to the IEEE NSSMIC conference, an accepted and presented abstract at the SNM Breast Cancer Imaging conference, and 3 conference proceedings articles.
