An X-ray diagnosis apparatus comprising:
- an X-ray tube configured to have a plurality of focal points and configured to emit X-rays from each focal point;
- a radiation quality filter configured to change radiation quality of the X-rays emitted from each of the focal points;
- and
- a mover configured to move the radiation quality filter in a direction along which the focal points are aligned,
- wherein the radiation quality filter is configured to change the radiation quality by adjusting energy of photons of the X-rays emitted from each of the focal points when the X-rays pass through the radiation quality filter.
