  • Patent number: 9029793
    Abstract: An imaging device (6) for scan-imaging radiation includes an imaging cell array (3) comprising an array of detector cells generating charge in response to incident radiation (1) and an array of pixel circuits each pixel circuit associated with a respective detector cell. The pixel circuit includes circuitry for accumulating plural radiation hit on an associated detector cell and transfer circuitry shifting upon command the accumulated value of all pixels by one step in one dimension (e.g., row by row). The imaged object (2) moves at a speed VOPT (7) with respect to the radiation source and the imaging detector (or source and detector move at ?VOPT with respect to the object) on which the accumulated values are shifted are with VTDI (8). VTDI may equal VOPT in value and direction. Thus, a value is accumulated in a moving information package using multiple pixels (10) and referring directly to a location on the moving object. The accumulated values are read out along one edge of the pixel array.

  • Patent number: 6552319
    Abstract: An imaging device for radiation imaging is an array of image cells. The array of image cells consists of an array of detector cells and an array of image cell circuits. Each detector cell is connected to the corresponding cell in the array of image cell circuits. Each individual cell in the detector cell array generates a charge based on the radiation that hits the cell. Each cell in the array of image cell circuits accumulates the charge on a storage capacitor. The storage capacitor can be, for example, the gate of a transistor. Single cells in the array of image cells can be grouped together to form larger area super cells. The size of the super cell can be controlled by control signals, which select the operating mode. The output from a cell, a single cell or a super cell, is read out in current mode and is scaled according to the size of the cell. Several modes can be implemented in the imaging device.

The output from a cell, a single cell or a super cell, is read out in current mode and is scaled according to the size of the cell. The read out line is pre-charged prior to read out to reduce the effect of parasitic capacitance in the read out line.
