Abstract: A mobile X-ray capturing apparatus includes an X-ray tube for irradiating an object with X ray, an arm for holding the X-ray tube, and a support pillar for holding the arm so as to facilitate arrangement of units. Further, the mobile X-ray capturing apparatus includes an arm energizing unit provided with an electrode incorporated in the arm for supplying power or a signal necessary for the X-ray tube, and a support pillar energizing unit provided with an electrode incorporated in the support pillar for supplying the power or the signal to the arm.

Abstract: A preliminary dark image acquisition unit 43 images a first preliminary dark image in each accumulation time, in advance, by accumulating a charge in at least one or more different accumulation times in a sensor 4 under a condition that the X ray is not irradiated. An X-ray image imaging unit 41 controls an irradiation of an X ray to image an X-ray image, selects an accumulation time corresponding to an X-ray irradiation time from among the accumulation times, and sets an accumulation time of a charge in the sensor 4 when the X-ray image is imaged to the selected accumulation time. The X-ray image imaging unit 41 images the X-ray image by accumulating the charge in the sensor 4 for the selected accumulation time. An offset correction unit 46 performs offset correction on the X-ray image based on the first preliminary dark image.
