Monolithic-based positron emission tomography (PET) detectors have become an attractive alternative to traditional pixelated scintillator modules. One of the main limiting factors to further expand the use of the monolithic approach in commercial PET

PURPOSE: We characterize the performance of a dualsided position-sensitive sparse sensor (DS-PS3) array detector for positron emission tomography (PET). The DS-PS3 detector is designed as a high performance, cost effective PET detector for organ-spec

The GE Discovery MI PET/CT system has a modular digital detector design allowing three, four, or five detector block rings that extend the axial field-of-view (FOV) from 15 to 25 cm in 5 cm increments. This study investigated the performance of the 5

Purpose Currently, single-photon emission computed tomography (SPECT)/computed tomography (CT) lung phantoms are commonly constructed using polystyrene beads and interstitial radioactive water. However, this approach often results in a phantom with a

We are currently building the PET/X scanner, which is a breast positron emission tomography (PET) scanner combined with a standard X-ray mammography system. The role for the PET/X scanner is to precisely measure changes in radiotracer uptake after an

PET detectors use signal multiplexing to reduce the total number of electronics channels needed to cover a given area. Using measured thin-beam calibration data, we tested a principal component based multiplexing scheme for scintillation detectors. T

A PET detector featuring a pseudo-monolithic crystal is being developed as a more cost-effective alternative to a full monolithic crystal PET detector. This work evaluates different methods to localize the scintillation events in quartered monolithic
