Patent ID: 7864921

Claim:
A radiation image detecting apparatus, comprising: a radiation source for irradiating radiation; a radiation detector for detecting radiation, which is irradiated by the radiation source onto a subject and which has passed through the subject, as a radiation image; scattered radiation removing means for removing scattered components of the radiation, provided on the radiation detector toward the side onto which the radiation is irradiated; reciprocal drive means, for reciprocally moving the scattered radiation removing means in one of a main direction and a sub direction of the radiation detector; image correcting means, for correcting the radiation image which is obtained by the radiation detector by detecting the radiation which has passed through the subject with a reference image; and irradiation control means, for controlling the irradiation of radiation onto the radiation detector; the irradiation control means controlling irradiation of the radiation during obtainment of the reference image such that the irradiation is ceased after the scattered radiation removing means is reciprocally moved for k periodic reciprocal motions (k is an integer greater than or equal to 1) from initiation of the irradiation, and controlling irradiation of the radiation during obtainment of the radiation image such that the irradiation is ceased after the scattered radiation removing means is reciprocally moved for m periodic reciprocal motions (m is an integer greater than or equal to 1).
