摘要: A radiation imaging detector has a scintillator array to be optically and mechanically coupled to a photodiode array, such that scintillator segments of the scintillator array are positioned over and aligned with respective pixels of the photodiode array. A metallic grid is deposited on the photodiode array to provide sufficient optical contrast for accurate visual alignment of the scintillator and photodiode arrays during fabrication. The metallic grid additionally serves to lower the series resistance of the photodiode entrance electrode. After alignment of the arrays, the upper surface of the scintillator array is closed by a reflective structure.

摘要: An multi-modality imaging system for imaging of an object under study that includes a magnetic resonance imaging (MRI) apparatus and an MRI-compatible single-photon nuclear imaging apparatus imbedded within the RF coil of the MRI system such that sequential or simultaneous imaging can be done with the two modalities using the same support bed of the object under study during the imaging session.

摘要: An avalanche drift photodetector (ADP) incorporates extremely low capacitance of a silicon drift photodetector (SDP) and internal gain that mitigates the surface leakage current noise of an avalanche photodetector (APD). The ADP can be coupled with scintillators such as CsI(Tl), NaI(Tl), LSO or others to form large volume scintillation type gamma ray detectors for gamma ray spectroscopy, photon counting, gamma ray counting, etc. Arrays of the ADPs can be used to replace the photomultiplier tubes (PMTs) used in conjunction with scintillation crystals in conventional gamma cameras for nuclear medical imaging.

摘要: Embodiments relate to an imaging system that includes a collimator assembly having two or more pinhole apertures therein. In one embodiment, the imaging system is configured so that two or more of the pinhole apertures have different focal lengths. The imaging system further includes a detector assembly configured to generate one or more signals in response to gamma photons that pass through the two or more pinhole apertures. Additional embodiments also relate to methods of changing collimator performance and methods of imaging a volume.
