In storage phosphor radiography a latent x-ray image of a patient is stored in a storage phosphor. A storage phosphor reader converts the latent image into an x-ray image signal. A patient identifying and exam collection bar code system provides patient identification and x-ray exam data at the time of the exam which is matched with the x-ray image signal in the reader.

Patient identification and x-ray exam data collection bar code system

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.
