Commissioning and Characterization of a Dedicated High Resolution Breast PET Camera

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). These LYSO crystal arrays contain 64 1mm3 crystal elements. The modules are organized in cartridges built out of 8 layers of 16 modules each. During this funding cycle two cartridges were constructed and operated in coincidence. Intrinsic spatial resolution was determined to be 0.85 mm. Software was written to perform calibration of the subsystem consisting of 512 PSAPDs. A global energy resolution of 10.62 +/ 0.04% FWHM ( at 511 keV) was obtained. Reportable outcomes include 2 peer reviewed publications, 2 abstracts submitted to the IEEE NSS-MIC conference, and 3 conference proceedings articles.
