摘要： A radiation detector having a fiber optic wedge with a plurality of parallel optical fibers is provided for yielding a more cost-effective radiation detector by reading out more scintillator elements or crystals per photodetector surface area. The fiber optic wedge provides a cost efficient method for increasing the number of scintillators that may be read out by a single position-sensitive photodetector of the radiation detector, such as a PET camera.

摘要： APD-based PET modules are provided for use in combined PET/MR imaging. Each module includes a number of independent, optically isolated detectors. Each detector includes an array of scintillator (e.g. LSO) crystals read out by an array of APDs. The modules are positioned in the tunnel of a MR scanner. Simultaneous, artifact-free images can be acquired with the APD-based PET and MR system resulting in a high-resolution and cost-effective integrated PET/MR system.
