摘要： In nuclear imaging, when a gamma ray strikes a scintillator, a burst of visible light is created. That light is detected by a photodetector and processed by downstream electronics. It is desirable to harness as much of the burst of light as possible and get it to the photodetector. In a detector element (18), a first reflective layer (44) partially envelops a scintillation crystal (34). The first reflective layer (44) diffuses the scintillated light. A second reflective layer (46) and a support component reflective layer (48) prevent the light from leaving the scintillation crystal (34) by any route except a light emitting face (36) of the scintillator (34). In another embodiment, a light concentrator (50) is coupled to the scintillator (34) and channels the diffuse light onto a light sensitive portion of a photodetector (38). The reflective layers (44, 46, 48) and the concentrator (50) ensure that all or nearly all of the light emitted by the scintillator (34) is received by the photodetector (38).

摘要： A scintillator (18) includes radioactive elements which emit radiation of a characteristic energy, such as lutetium 176 , which emits 202 keV and 307 keV γ-rays. The scintillators have light output levels that vary and photomultiplier tubes that respond to the light scintillations tend to drift. When a scanner (10) is not generating diagnostic images, the photomultiplier tubes detect scintillations from the lutetium176 radiation. A self- calibration processor (40) adjusts the gain for each photomultiplier tube such that its output peak corresponds to 202 keV or 307 keV and adjusts a scaling factor for PMT outputs corresponding to each scintillator such that the output peaks have a common amplitude.

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： When constructing a nuclear detector module in a gantry, a plurality of overlapping light guide modules (10) are mounted to the gantry in a spaced-apart fashion, and a plurality of underlapping light guide modules (12) are mounted in between each pair of overlapping light guide modules (10). Each of the underlapping modules and the overlapping modules includes a scintillation crystal array (16) on an interior surface thereof, and a plurality of PMTs on an exterior surface thereof. Overlapping modules (10) have overlapping structures (22) that interface with underlapping structures (18) on the underlapping modules (12) and thereby eliminate a seam directly beneath PMTs that overlap the crystal arrays of both an overlapping module and an underlapping module. Optical grease is used to form a resilient grease coupling and reduce light scatter between the underlapping and overlapping modules.

摘要： A radiation detector (20, 20') includes scintillator pixels (30) that each have a radiation-receiving end, a light-output end, and reflective sides extending therebetween. The reflective sides have a reflection characteristic (40, 40', 42, 44) varying between the radiation-receiving end and the light-output end such that a lateral spread of light emanating from the light-output ends of the scintillator pixels responsive to a scintillation event generated in one of the scintillator pixels depends upon a depth of the scintillation event in the scintillator pixel. A plurality of light detectors (46) optically communicate with the light-output ends of the scintillator pixels to receive light produced by scintillation events.
