Abstract
A calibration technique for a storage phosphor reader which accomplishes the following; a) finds the leading edge of the storage phosphor being read by the reader; b) finds the front and rear edges of the storage phosphor in order to adjust the length of the line scan to the dimension of the storage phosphor in the line scan direction; c) verifies that the photodetectors of the reader are functioning; d) adjusts each photodetector signal channel to the appropriate gain; and e) generates a correction signal to correct nonuniformities of the photodetector signal output.
