  New detector approaches in Positron Emission Tomography imaging will play an
important role in reducing costs, lowering administered radiation doses, and
improving overall performance. PETALO employs liquid xenon as the active
scintillating medium and UV-sensitive silicon photomultipliers for
scintillation readout. The scintillation time in liquid xenon is fast enough to
register time-of-flight information for each detected coincidence, and
sufficient scintillation is produced with low enough fluctuations to obtain
good energy resolution. The present simulation study examines a full-body-sized
PETALO detector and evaluates its potential performance in PET image
reconstruction.
