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 the two cartridges constructed in the previous cycle were further characterized in terms of uniformity and isotropy of the spatial resolution in 3D. Using multiple radioactive sources we also confirmed a linear response. Furthermore, improved calibration and thermal regulation yielded improved images compared to the ones presented in the FY03 report. Reportable outcomes include 3 conference records, 1 book chapter, and 3 submissions to peer reviewed journals, these are still under review.
