<P>PROBLEM TO BE SOLVED: To efficiently correct a radiological image which is acquired while reciprocating a scattered radiation removing means. <P>SOLUTION: An image processing device 100 performs a shading correction, a gain correction, or the like on the radiological image P at the time of detecting radiation transmitting through a subject by a radiation detector while reciprocating the scattered radiation removing means 20 by using a reference image. In the case of acquiring the reference image Pref, an exposure control means 50 controls to end the emission of radiation when the scattered radiation removing means 20 makes reciprocating movements for k-cycles (k is an integer equal to 1 or larger) from the beginning of the emission of the radiation. On the other hand, in case of acquiring the radiological image, the exposure control means 50 controls to end the emission of the radiation when the scattered radiation removing means makes reciprocating movements for m cycles (m is an integer equal to 1 or larger) from the beginning of the emission of the radiation. <P>COPYRIGHT: (C)2009,JPO&INPIT |
