OPTICAL PROCESSING DEVICE AND METHOD, RADIOGRAPHIC CASSETTE, DOSIMETRIC MODULE AND RADIATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a device and method processing light obtained from an X-ray for improving image quality. SOLUTION: A means is provided filtering light by a cut-off frequency retaining a first portion of a temperature independent spectrum of light emitted from a light emitting body and blocking a second portion of a light spectrum representing a shift dependent on temperature. A radiographic cassette, a dosimetric module, and a radiation device including such filtering means are also provided.
