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 1time phase of 1beat to obtain a radiographic image. Thereafter, X-ray irradiations are performed sequentially at 2time phase of 2beat, at 3time phase of 3beat, at 4time phase of 4beat, and at 5time phase of 5beat 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 1to 5time phases may be obtained with high resolution.
