First steps toward fast PET reconstruction

Meeting • 30 May 2017

Abstract
In this talk, I will describe my recent work on positron emission tomography (PET) reconstruction. PET is a medical imaging modality that can be used to observe metabolic processes in vivo. As with X-ray CT, the measured data correspond to line integrals of the volume to be reconstructed. However, these measurement do not fall on a regular grid, but rather, a complicated pattern determined by the geometry of the scanner. I will give a short introduction to the physics and geometry of PET, then discuss my efforts to resample PET data into a form amenable to the fast algorithms we developed for parallel-ray CT.
