X-ray diagnosis apparatus and non-transitory computer readable storage medium

An X-ray diagnosis apparatus, comprising:

• an X-ray irradiator configured to irradiate X-rays;
• an imager configured to image an identifier that identifies a position of an X-ray detector which detects X-rays;
• a support member configured to support the X-ray irradiator to be movable in a plurality of directions;
• and
• processing circuitry configured to
• calculate, based on the identifier shown on an image imaged by the imager, a relative position of the X-ray irradiator relative to the X-ray detector and an irradiation position of the X-ray irradiator that meets the X-ray imaging condition for which the relative position of the X-ray tube is predetermined;
• calculate a plurality of movement routes including a movement amount in each of the plurality of directions from the relative positions to the irradiation positions;
• select, based on a priority of each of the preset plurality of directions, one movement route from the plurality of movement routes;
• output, the selected one movement route as movement information indicating the movement amount and a movement direction of the X-ray irradiator from the relative position to the irradiation position;
• and
• control, based on the output movement information, the support member to move the X-ray irradiator to the irradiation position.
