Monte Carlo sensitivity study of a long axial FOV PET scanner with patient adaptive rings

摘要

In this work, we present the simulation results of a compact whole body PET design and an optimized longer axial FOV PET using monolithic detectors. The compact design is a simulation of the proposed European PET system (PET2020) of 70cm bore and axial FOV of 70cm optimized for cost and single organ imaging. The total number of detectors and readout is ‘only’ 2-3 x higher than the current PET-CT systems. The extended FOV system without any additional detectors represents a research upgrade for the compact system to enhance FOV and spatial resolution at no extra cost of detectors for smaller objects than the available bore diameter.
