BGO as a hybrid scintillator / Cherenkov radiator for cost-effective time-of-flight PET.
Due to detector developments in the last decade, the time-of-flight (TOF) method is now commonly used to improve the quality of positron emission tomography (PET) images. Clinical TOF-PET systems based on L(Y)SO:Ce crystals and silicon photomultipliers (SiPMs) with coincidence resolving times (CRT) between 325 ps and 400 ps FWHM have recently been developed. Before the introduction of L(Y)SO:Ce...
متن کاملPET camera performance design evaluation for BGO and BaF2 scintillators (non-time-of-flight).
Bismuth germanate (BGO) and barium fluoride (BaF2) scintillators are presently used in positron emission tomegraphy (PET) cameras. This study evaluates the important PET performance parameters of image resolution, true sensitivity, scatter background, accidental background, and realistic maximum radioactivity in the field of view for both BGO and BaF2 in an identical non-time-of-flight, whole-b...
متن کاملAnode Position and Last Dynode Timing Circuits for Dual-Layer BGO Scintillator With PS-PMT Based Modular PET Detectors
New high spatial resolution positron emission tomography (PET) detectors for small animal and breast imaging have been developed. In these detectors, position-sensitive photomultipliers (R7600-C12) and dual-layer pixelated bismuth germanate (BGO) crystals are employed to detect and localize gamma rays. Modified high-voltage dividers with last dynode readout circuits, front-end anode position, a...
متن کاملOptical Properties of the Dirc Fused Silica Cherenkov Radiator
The DIRC detector is successfully operating as the hadronic particle identification system for the BaBar experiment at SLAC. The production of its Cherenkov radiator required much effort in practice, both in manufacture and conception, which in turn required a large number of R&D measurements. One of the major outcomes of this R&D work was an understanding of methods to select radiation hard an...
متن کاملA Hybrid Metaheuristic Algorithm for the Vehicle Routing Problem with Delivery Time Cost
This paper addresses the Vehicle Routing Problem with Delivery Time Cost. This problem aims to find a set of routes of minimal total costs including the travelling cost and delivery time cost, starting and ending at the depot, in such a way that each customer is visited by one vehicle given the capacity of the vehicle to satisfy a specific demand. In this research, a hybrid metaheuristic approa...
