Title:
RADIATION DETECTOR
Document Type and Number:
Japanese Patent JP2018059725
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a radiation detector that can optimize a photographing of a dark image.SOLUTION: A radiation detector related to the embodiment comprises: a plurality of detection units for detecting radiation directly or in cooperation with a scintillator; and a control unit for retrieving a signal charge from each of the plurality of detection units. The control unit retrieves the signal charge from each of the plurality of the detection units in a state in which the radiation is not irradiated; obtains nth data of dark images; calculates the difference between the nth data of dark images and the already-acquired (n-1)th data of dark images; and changes at least one of the photographing interval time of the dark images and the number of photographing times of the dark images on the basis of the calculated difference.SELECTED DRAWING: Figure 5
