摘要： An x-ray detector includes a scintillator, a sensor array, processing circuits, and a ceramic layer. The ceramic layer overlays the processing circuits. The pixel architecture of the detector utilizes a technique similar to a CCD array to shift data from the array. The detector preferably utilizes 4-side abuttable sensor arrays having imbedded shift registers and bond pads superimposed over the pixel array in the upper metallization layers of the sensor. An alternative embodiment incorporates a silicon-on-insulator substrate to produce a monolithic large area substrate and a contiguous uninterrupted pixel array over the entire imaging surface.

摘要： A raster scan digital display system of the type in which consecutive locations in a buffer store are accessed to provide a picture element data stream, has means to increase the number of bits in each picture element data group. Each applied buffer store address is compared with a preselected address. When equality is detected, the value of the extra picture element bits is set, and a new preselected address is generated. The value of the extra picture element bits remains constant until equality between the new preselected address and an applied buffer store address is detected, when the extra bit value is changed and a new preselected address is provided.
