Title:
放射線検出システム
Document Type and Number:
Japanese Patent JP4789332
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To miniaturize a radiation pickup device and to eliminate the dispersion of an exposure of radiation. SOLUTION: This radiation detecting system is provided with a radiation source emitting the radiation to a subject and a detector detecting the radiation emitted from a radiation source and transmitting through the subject. This system has a storage means storing a total incident amount necessary for the detector of furorographing beforehand, a calculation means detecting the total incident amount of the radiation detected by the detector, when emitting a prescribed radiation from the radiation source in prior to the furorographing of the subject and calculating the ratio of the total incident amount of the detector relative to the total emission amount of the radiation source, and a determination means determining the total emission amount emitting from the radiation source toward the subject based on the calculated result of the calculation means and the total incident amount necessary for fluorographing stored the storage means, when furorographing the subject.
