Radiation image information reading apparatus with radiation conversion panel, and method of correcting sensitivity of radiation conversion panel

摘要

Corrective image data obtained by reading a stimulable phosphor sheet which is uniformly irradiated with a radiation are masked, and added and averaged into reference data. The ratio between the reference data and the corrective image data is generated as sensitivity correcting data. Desired radiation image information is then read from the stimulable phosphor sheet, corrected by the sensitivity correcting data, and outputted to an external image processing apparatus.
