Abstract
The apparatus includes a two-coordinate array of radiation sensitive devices each operable to cause the storage of a charge proportional to the intensity and duration of radiation received. A storage element is associated with each sensitive circuit and a transfer mechanism is operable to transfer the charge from each sensitive circuit to its storage element to define a radiation image frame. A register is arranged in the same two coordinate array, and a shift mechanism operates to transfer charge from the storage elements to the register in parallel bit streams defined by one of the two coordinates. Differential detectors compare corresponding bits shifted into and out of the register and the presence of a detector output exceeding a threshold level causes the detector outputs to be sampled into an output register. The contents of the output register are shifted out serially to determine the position in the radiation image frame of each output register bit position producing a detector output.
