Title:     Design and Performance of Liquid Xenon Detectors for PET

Abstract: This talk is about studying the interactions of 511 keV photons in liquid xenon (LXe) detectors for applications to positron emission tomography (PET). The advantages of LXe for PET compared to currently used methods include improved energy resolution (<10% FWHM) by combining information from measuring the ionization as well as the scintillation light. Results obtained for the energy resolution with a small prototype will be presented. The approach also allows for a 3-D sub-mm spatial resolution eliminating parallax errors. A concept for a micro-PET detector that takes advantage of the improved performances achieved by measuring light and charge in LXe will be presented and its performance was evaluated with simulation studies.

Stimulants available 15 minutes before the talk.
