According to one embodiment, an X-ray computed tomography apparatus includes an X-ray tube to generate X-rays, X-ray detector to detect the X-rays transmitted through an object, top to place the object, rotation driving unit to rotate a rotating frame with the X-ray tube and the X-ray detector around the object, movement driving unit to relatively reciprocate the rotating frame and the top over a plurality of times along a long-axis direction of the top, and scan control unit to control the movement driving unit in the relative reciprocal movement such that moving loci of the X-ray tube corresponding to the respective forward movements are matched with each other and moving loci of the X-ray tube corresponding to the respective backward movements are matched with each other.
