Abstract:
1. A dynamic radiographic image obtaining apparatus for obtaining a dynamic radiographic image of a periodically moving subject, the apparatus: a dynamic signal detecting means for detecting a dynamic signal of the subject; an image obtaining means for obtaining a plurality of radiographic images of the subject by irradiating radiation on the subject from one direction and detecting the radiation passed through the subject; a control means for allocating a plurality of time phases to each of predetermined periods of the dynamic signal detected by the dynamic signal detecting means, and controlling the image obtaining means such that the radiographic images of the subject are obtained at respective time phases that differ from one predetermined period to another; a storing means for storing the radiographic images obtained with the time phase information correlated therewith; and a dynamic image generating means for generating the dynamic radiographic image of the subject by arranging the radiographic images obtained in the order of the time phases, each being stored and correlated with each corresponding radiographic image among the radiographic images, from a radiographic image obtained at a time phase closest to a starting point of the each of the predetermined periods of the dynamic signal further comprising an interpolated image generating means for generating an image through interpolation from the radiographic images already obtained, which corresponds to a time phase that differs from each of the time phases at which the radiographic images are obtained.
