摘要： A gamma ray imaging system for providing high resolution images includes a collimator plate with an array of multiple holes which image a gamma emitting object onto a semiconductor gamma detector pixel array coupled to a signal processor. The collimator holes are smaller than half the pixel pitch. The detector array is moved in steps, with a step-size equal to the pitch of the collimator holes, to successive imaging positions. The hole locations and imaging positions are such that gamma photons do not fall on the dead areas of the pixels. An electronic processing unit constructs from the pixel signals produced at each imaging position, a set of independent equations and solves them to derive the exact image signal of each irradiated area, and uses this data to compose and a display a high resolution gamma image of the object.

摘要： A pixelated detector assembly comprising a stack of thin detector crystals, each detector crystal having a pair of planar surfaces bound by edges substantially thinner than the dimensions of the surfaces. The stack is disposed such that the radiation to be detected is incident on one set of edges of the stack of detector crystals. The dimension of the planar surfaces in the general direction of incidence of the radiation incidence is sufficient to ensure that substantially all of the high energy photons to be detected are absorbed within the depth of the detector assembly. Each of the detector crystals has a two-dimensional pixelated anode array formed on one of its planar surfaces. A cathode is formed on its opposite planar surface, preferably covering substantially all of the surface. The position of interaction of a photon in the plane perpendicular to the direction of the incident radiation, is determined by which of the detector crystals in the stack detects the absorption, and by which of the rows of pixelated anodes in that crystal detects the absorption. The depth of interaction of a photon is determined by the location of the particular anode pixel in the above-mentioned row of pixelated anodes where the photon absorption is detected. The detector assembly is thus able to detect the point of interaction of a photon in all three dimensions.

摘要： A novel semiconductor detector device, consisting of several layers of two dimensional detector modules each module being divided into an array of separate detector cells by means of the pixelation of the electrodes on the surfaces of the modules. The superimposed detector cells in equivalent positions in each layer are in electrical contact with those in the two immediately adjacent layers, such that the whole device effectively becomes a two dimensional array of stacks of individual detector cells, with a common bottom electrode. Current in each detector cell stack, induced by the absorption of a high energy photon in that stack, is measured by means of an integrating charge sensitive amplifier attached to each anode at the top of each cell stack. A large area gamma-ray detector, sufficiently thick to absorb the high energy photons arising from electron-positron annihilation events, is thus obtained, but without the expense associated with the production of a single detector crystal of the required thickness.
