Abstract: The X-ray diagnostic apparatus according to any of embodiments includes an X-ray tube, an X-ray detector and processing circuitry. The X-ray tube is configured to irradiate an imaging region of a subject with X-rays. The X-ray detector is configured to detect the X-rays. The processing circuitry is configured to acquire an incident angle of the X-rays corresponding to a clinical purpose of the imaging region, and acquire image data from an image sensor that images the imaging region. The processing circuitry is configured to rotate the X-ray tube in accordance with the acquired incident angle of the X-rays, and slide a position of a central path of the X-rays with respect to the imaging region based on the image data.

Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an X-ray irradiator, a scatterer, a grid, and a detector. The X-ray irradiator irradiates X-rays. The scatterer is provided between the X-ray irradiator and an object, that scatters the irradiated X-rays. The grid is provided between the scatterer and the object, that transmits the scattered X-rays within a predetermined angular range. The detector detects X-rays transmitted through the object together with an incident angle of the X-rays.

Abstract: A wrap replacing apparatus according to the embodiments includes: an insertion port into which a medical device wrapped in a first bag is inserted; a peeler configured to peel off the first bag from the medical device inserted into the insertion port; a wrapper configured to wrap in a second bag the medical device from which the first bag is peeled off; and a take-out port from which the medical device wrapped in the second bag is taken out.
