RADIATION IMAGING APPARATUS

PROBLEM TO BE SOLVED: To shorten medical work using an implant member by easily acquiring life-sized image information relating to a portion where the implant member is embedded in a subject. SOLUTION: A first radiation imaging apparatus 10A having a radiation source and a radiation conversion panel 16 for detecting radiation emitted from the radiation source and transmitted through the subject with the implant member embedded therein and converting it to radiation image information comprises: a measuring means 104 for measuring the size of the image of a portion of the implant member in the radiation image information from the radiation conversion panel 16; an actual measurement value acquiring means 106 for acquiring an actual measurement value indicating the actual size of a portion of the implant member; and a life-size correcting means 110 for executing life-size correction on the basis of a measurement value from the measuring means 104 and the acquired actual measurement value and turning the radiation image information from the radiation conversion panel 16 to life-sized image information.
