Claim Text:
1. A mobile X-ray diagnostic apparatus, comprising: an X-ray source irradiating an X-ray; an X-ray detector detecting the X-ray transmitted through an object; a holding unit holding the X-ray source and the X-ray detector facing each other; an X-ray detector rotation driving unit rotationally driving the X-ray detector for the holding unit; a movably main body supporting the holding unit on a floor surface; a first detection unit detecting a rotation amount of the main body in a horizontal surface by a movement on the floor surface; an X-ray detector control unit controlling a rotary drive of the X-ray detector using the X-ray detector rotation driving unit based on a detection result in the first detection unit; a target rotation amount calculation unit that calculates a target rotation amount required to change an orientation of the X-ray detector that moves with the main body to an original orientation of the main body before the movement based on a first rotation amount detected by the first detection unit; an X-ray detector rotation control unit that commands the X-ray detector rotation driving unit to rotate the X-ray detector based on the target rotation amount calculated by the target rotation amount calculation unit; a rotatably supporting unit supporting the holding unit for the main body; and a second detection unit detecting a second rotation amount of the supporting unit: wherein the target rotation amount calculation unit calculates the target rotation amount based on the first rotation amount detected by the first detection unit and the second rotation amount detected by the second detection unit.
