摘要： When employing specular reflective material in a scintillator crystal array, light trapping in the crystal due to repetitive internal reflection is mitigated by roughening at least one side(16) of each of a plurality of pre-formed polished scintillator crystals. A specular reflector mate¬ rial (30) is applied (deposited, wrapped around, etc.) to the roughened crystals, which are arranged in an array. Each crystal array is coupled to a silicon photodetector (32) to form a detector array, which can be mounted in a detector for a functional scanner or the like.

摘要： The present invention relates to a pixellated detector with an enhanced structure to enable easy pixel identification even with high light output at crystal edges. A half-pixel shift between scintillator crystals (50) and detector pixels (12) enables the identification of a crystal (50) from four detector pixels (12) instead of nine pixels in case of optical crosstalk. Glass plates without any mechanical structuring may be used as a common substrate (60) for detectors and scintillators.

摘要： A light transmitting element such as a scintillating element (50) or an optic fiber (50') has side surfaces coated with a metamaterial (62) which has an index of refraction less than 1 and preferably close to zero to light transmitted in the light transmitting element. A photonic crystal (80) or metamaterial layer optically couples a light output face of the light transmitting element with a light sensitive element (52), such as a silicon photomultiplier (SiPM). A thin metal layer (64) blocks optical communication between adjacent scintillating elements (50) in a radiation detector (22), such as a radiation detector of a nuclear imaging system (10).

摘要： When designing detector arrays for diagnostic imaging devices, such as PET or SPECT devices, a virtual detector, or pixel, combines scintillator crystals (10, 20, 40) with photodetectors (12) in ratios that deviate from the conventional 1 : 1 ratio. For instance, multiple photodetectors can be glued to a single crystal to create a virtual pixel (10, 20, 40) which can be software-based or hardware-based. Light energy and time stamp information for a gamma ray hit on the crystal can be calculated using a virtualizer processor or using a trigger line network and time-to-digital converter logic. Additionally or alternatively, multiple crystals (54) can be associated with each of a plurality of photodetectors (52). A gamma ray hit on a specific crystal is then determined by a table lookup of adjacent photodetectors (52) that register equal light intensities, and the crystal (54) common to such photodetectors (52) is identified as the location of the hit.

摘要： In a combined system, a magnetic resonance (MR) scanner includes a magnet (10, 110) configured to generate a static magnetic field (B0) at least in a MR examination region (12) from which MR data are acquired. Radiation detectors (40, 41, 140) are configured to detect gamma rays generated by positron-electron annihilation events in a positron emission tomography (PET) examination region (70). The radiation 5 detectors include electron multiplier elements (60, 160) having a direction of electron acceleration (ae) arranged substantially parallel or anti-parallel with the static magnetic field (B0). In some embodiments, the magnet is an open magnet having first and second spaced apart magnet pole pieces (14, 15) disposed on opposite sides of a magnetic 10 resonance examination region, and the radiation detectors include first and second arrays (40, 41) of radiation detectors disposed with the first and second spaced apart magnet pole pieces.
