Title: Dynamic radiographic image obtaining method and apparatus

Abstract: A method and apparatus for obtaining a dynamic radiographic image with enhanced resolution, in which an electrocardiogram of a subject is obtained, and five time phases are allocated to each cardiac beat period (1 second). The initial X-ray irradiation is performed at 1.sup.st time phase of 1.sup.st beat to obtain a radiographic image. Thereafter, X-ray irradiations are performed sequentially at 2.sup.nd time phase of 2.sup.nd beat, at 3.sup.rd time phase of 3.sup.rd beat, at 4.sup.th time phase of 4.sup.th beat, and at 5.sup.th time phase of 5.sup.th beat to obtain respective radiographic images. The five radiographic images obtained are combined at the time interval of 0.2 seconds to be displayed as a motion image. The time interval between the irradiations of the X-ray is 1.2 seconds, so that image signals corresponding to 1.sup.st to 5.sup.th time phases may be obtained with high resolution.
