<p>Sensitivity information on the sensitivities of the channels of an X-ray flat detector (3) is used for sensitivity correction of an image formed by irradiation of a subject with X-rays and read out of the X-ray flat detector (3). The collection of the sensitivity information is started when a signal for starting the collection of the sensitivity information is sent to a sensitivity information collection control means (11) from an operator console (12). The sensitivity information collection control means (11) sends an irradiation start signal for starting irradiation with calibration light to calibration light control means (10). The calibration light control means (10) controls calibration light irradiation means (9) so that a desired intensity of light may be applied to the inside of the X-ray flat detector (3). Thus, a calibration light reception signal outputted from the X-ray flat detector (3) is stored as sensitivity information in sensitivity information storage means (5). Consequently, such sensitivity information can be collected without irradiating the X-ray flat detector (3) with X-rays. Therefore an X-radiation image diagnosis apparatus in which the sensitivity information for correcting the sensitivities of the channels of an X-ray flat detector can be collected without irradiating the X-ray flat detector with X-rays is realized.</p> |
