Abstract
An image acquisition unit acquires a radiographic image set including a plurality of radiographic images, which have been generated by alternately irradiating a subject with radiation emitted from a plurality of radiation sources provided at different positions and alternately detecting the radiation transmitted through the subject using one detection unit, at a predetermined time interval. A feature point detection unit detects at least one common feature point in the subject from each of the plurality of radiographic images included in the radiographic image set. A positional information derivation unit derives three-dimensional positional information of the at least one feature point in the subject using a positional relationship between a position of the at least one feature point detected from each of the plurality of radiographic images on a detection surface of the detection unit and positions of the plurality of radiation sources.
