Abstract: 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.

Abstract: A method is disclosed for determination of positron-emission measurement information about a body area which is affected by at least one periodic movement process of an examination object during the course of positron-emission tomography. In at least one embodiment, the method includes a positron-emission measurement being carried out in the body area to be examined of the examination object in order to determine functional positron-emission measurement information, and recording, at the same time as the positron-emission measurement, anatomical measurement information about the body area to be examined is recorded, restricted to one recording plane, for at least one measurement time period, using an anatomical imaging method with high time resolution, in particular using a computed-tomography method.

Abstract: PET detector modules are provided within a multi-dimensional magnetic field, to confine the range of emitted positrons from an object being imaged to improve spatial resolution of reconstructed PET images. Each module includes a number of independent, optically isolated detectors. Each detector includes an array of scintillator crystals read out by an array of APDs (avalanche photodiodes).

Abstract: A scintillation detector for PET imaging devices includes a wavelength shifting material for shifting the emission wavelength of a scintillator toward the peak wavelength sensitivity of a photodetector array coupled to receive light from the scintillator. Preferably the scintillator is an LSO scintillator and the photodetector array is a silicon-based array such APDs or SiPMs.
