RADIATION DETECTOR, RADIOLOGICAL DIAGNOSTIC APPARATUS AND METHOD FOR DETERMINING CHARGE SHARING

摘要

To reduce erroneous detection due to charge sharing.SOLUTION: A radiation detector according to the embodiment comprises a plurality of main electrodes, auxiliary electrodes, and a determination part. The plurality of main electrodes detect electrons according to the incidence of radiation from a semiconductor element. The auxiliary electrodes are arranged between the plurality of main electrodes, detect the electrons according to the incidence of radiation from the semiconductor element, and have smaller dimensions in the arrangement direction than those of the main electrodes. The determination part makes a determination regarding charge sharing based on the outputs of the main electrodes and the auxiliary electrodes.SELECTED DRAWING: Figure 4
