RADIOGRAPH INFORMATION READER

摘要

PROBLEM TO BE SOLVED: To easily obtain radiograph information for energy subtraction processing with respect to a radiograph information reader using a line light source and a line sensor. SOLUTION: The subtraction processing is performed corresponding to a pixel by respectively condensing stimulated luminescences M and M' emitted from both sides of a stimulable phosphor sheet 50 for radiation energy subtraction constituted by accumulating and recording two pieces of radiograph information where radiation energy absorption characteristics on the same subject are different each other by the line sensors 20 and 20' disposed on respective surface sides.
