摘要： A method and apparatus for correcting for the spatial distortions of scintillation cameras or similar image forming apparatus. The spatial distortion correction method accurately and precisely determines distortion correction factors in an off-line test measurement and analysis phase prior to actual on-line diagnostic use. The distortion correction factors are initially determined from image event data that is obtained during the test measurement phase by orthogonal line pattern images. Data from a uniform field flood image is also utilized during the test measurement phase to refine and modify the distortion correction factors utilizing the gradient of a function of the field flood image data. Scintillation camera image repositioning apparatus (18) is provided and includes a memory (108) having the correction factors stored therein in a predetermined array. During the on-line use of the scintillation camera (10) and associated image display system, the image repositioning apparatus (18) transforms the data from the scintillation camera (10) in accordance with the stored distortion correction factors. In a preferred arrangement, the image event data is repositioned or corrected event by event.

摘要： A positron emission tomography camera with the edges between the arrays of crystals offset in relation to the edges between the light detectors, allowing the use of circular photomultiplier tubes instead of the more expensive square ones. According to an aspect of the present invention the crystal arrays are formed by optically bonding slabs (40) of crystals into a "pre-array" and then cross cutting (42) the "pre-array" from one or more sides to form the final array (16). The grooves (42) may be optically treated, such as with white reflective fillers, for further optical control within the array.

摘要： Large scintillator array multiplexing apparatus and method in which individual scintillators (12) are coupled to fluorescent optical converters (25) that absorb the light emitted by the scintillators (12) and emit at longer wavelengths. Loss of light is minimized by maximizing total internal reflection of the longer wavelength emissions by the use of reflectors and mirrors. The wavelength-shifted radiation is conducted to electro-optic detectors (30) and (32) which, when activated, directly encode the location of the scintillator that has been excited by ionizing radiation. Using this method, scintillator arrays (10) consisting of thousands of individual scintillators (12) can be built without undue complexity or cost and the resolution of the imaging system can be enhanced beyond the range possible using prior art methods.

摘要： The crystal (1) is sealed by either glass-to-metal seals or epoxy to prevent moisture degradation within a housing. Combined with multiple barriers, the new configuration is long lasting and provide long life for the detector. The cladding layers (11, 23) and the mirror system (21) provide gas-free, high reflectivity crystal mirror surface. The mirror system (21) can be specular or diffusive. Curved shapes at the photodetector walls provide the first step in focusing light. Crystal (1) has an upper and lower truncated conical or pyramidal portions with rounded bottoms and tops. The truncated shapes encourage minimal internal reflections of photons generated in the crystal (1). The housing has upper and lower sections which follow the crystal (1) shape, and thin ring peripheral edges are welded together to avoid heat damage.

摘要： A positron emission tomography camera is provided having an array of scintillation crystals (16) placed adjacent other arrays to form an arcuate detection surface surrounding a patient area. Alternatively, the arrays may be placed in a planar configuration on opposing sides of the patient area. Either a three-dimensional image or a two-dimensional image can be formed from a patient's body placed within the patient area. Moreover, the edges between the arrays of crystals are offset in relation to the edges between the light detectors. Each light detector (14) is suitably positioned adjacent four adjacent quadrants of four respective arrays to simultaneously detect radiation emitted from the four quadrants of each array. Moreover, each crystal within the array is selectively polished and selectively bonded to adjacent crystals to present a cross-coupled interface which can tunably distribute light to adjacent light detectors.
