Image reconstruction and elongation artifact reduction for a dual-panel dedicated prostate PET scanner.

ABSTRACT:

Background

The development of PET scanners dedicated to high temporal and spatial resolution organ-specific imaging is an active research area, motivated by the need for cost reduction, improved lesion detectability and quantification in specific clinical scenarios, as well as by ongoing hardware and software innovations.

Purpose

This study investigates and compares various image reconstruction strategies for a dual-panel prostate-dedicated PET scanner (ProVision), which features four-layered dual-readout time-of-flight depth-of-interaction detectors and a 22-position acquisition protocol to improve angular coverage.

Materials and methods

A list-mode MLEM algorithm with multi-ray modeling was developed and optimized using a scaled NEMA image quality phantom to determi
