Automated technique for calibrating a storage phosphor reader.

摘要

An automated method for analyzing the photometric calibration and image quality performance characteristics of a high resolution storage phosphor reader (10). A custom fabricated, lead mask test target (104) is secured to a storage phosphor (106) and exposed using a standard medical x-ray source (100). A storage phosphor reader (10), to be calibrated, reads the exposed storage phosphor (106) to produce a digital x-ray image. The digital x-ray image is analyzed by means of a computer algorithm which presents analytic results in text and graphical form to isolate reader problems and to quantify calibration status of the reader (10). <IMAGE>
