An X-ray image pick-up method causes X-rays from an X-ray source to be irradiated on an object for picking up its image as passed through a filter capable of restricting any fluctuation in effective X-ray energy within +/-10%, and then the X-rays thus penetrated through the object to be picked up by an image pick-up means. Radiation dose with respect to patients as the object and eventually to doctors or X-ray operators is thereby minimized, while the image pick-up can be realized with a high resolution. <IMAGE> |
