Abstract

An X-ray diagnosis apparatus is configured to control at least one of the X-ray diaphragm which restricts the irradiation range of the X-ray and the compensation filter which attenuates the amount of the X-ray based on at least one of the rotation position or the position parallel to the body axis of the X-ray source.

a controller configured to control the compensation filter to move in a second direction, opposite to the direction of movement of the X-ray source, at a same speed as the movement of the X-ray source.

2. The apparatus of claim 1 , further comprising:

a diaphragm configured to restrict an irradiation range of the X-ray; and

a diaphragm controller configured to control the diaphragm based on the position of the X-ray source in the first direction.

3. The X-ray diagnosis apparatus according to claim 2 , wherein the movement apparatus is configured to move the position of the X-ray source in a longitudinal direction of the object.

4. The X-ray diagnosis apparatus according to claim 2 , wherein the diaphragm controller comprises:

a memory configured to store data of the irradiation range corresponding to the position of the X-ray source; and

a main controller configured to read the data from the memory based on the position of the X-ray.

5. The X-ray diagnosis apparatus according to claim 4 , wherein the memory is configured to store the data of the irradiation range corresponding to a plurality of positions of the X-ray source.

6. The X-ray diagnosis apparatus according to claim 2 , further comprising an operation unit configured to set the irradiation range on an X-ray fluoroscopic image.

7. The X-ray diagnosis apparatus according to claim 2 , wherein the movement apparatus is configured to move the position of the X-ray source along a flow direction of a contrast agent injected into the object, at a desired speed.

8. The X-ray diagnosis apparatus according to claim 2 , further comprising a bed on which the object is positioned.

9. The apparatus of claim 1 , further comprising:

a diaphragm configured to restrict an irradiation range of the X-ray;

a rotation apparatus configured to rotate a position of the X-ray source around the object; and

a diaphragm controller configured to control the diaphragm based on the position of the X-ray source.

10. The X-ray diagnosis apparatus according to claim 9 , wherein the diaphragm controller comprises:

a memory configured to store data of the irradiation range corresponding to the position of the X-ray source; and

a main controller configured to read the data from the memory based on the position of the X-ray.

11. The X-ray diagnosis apparatus according to claim 10 , wherein the memory is configured to store the data of the irradiation range corresponding to a plurality of positions of the X-ray source.

12. The X-ray diagnosis apparatus according to claim 9 , further comprising an operation unit configured to set the irradiation range on an X-ray fluoroscopic image when the X-ray stops being irradiated.

13. The X-ray diagnosis apparatus according to claim 9 , further comprising a bed on which the object is positioned.

14. The apparatus of claim 1 , further comprising:

an operation unit configured to set at least one of a virtual diaphragm or a virtual compensation filter on an X-ray fluoroscopic image.

15. The X-ray diagnosis apparatus according to claim 1 , wherein the movement apparatus moves the position of the X-ray source in a longitudinal direction of the object.

16. The X-ray diagnosis apparatus according to claim 1 , wherein the controller comprises:

a memory configured to store data of an amount of the X-ray corresponding to the position of the X-ray source; and

a main controller configured to read the data from the memory based on the position of the X-ray.

17. The X-ray diagnosis apparatus according to claim 16 , wherein the memory is configured to store the data of the amount of the X-ray corresponding to a plurality of the positions of the X-ray source.

18. The X-ray diagnosis apparatus according to claim 1 , further comprising an operation unit configured to set the amount of the X-ray on an X-ray fluoroscopic image.

19. The X-ray diagnosis apparatus according to claim 1 , wherein the movement apparatus is configured to move the position of the X-ray source along a flow direction of a contrast agent injected into the object at a desired speed.

20. The X-ray diagnosis apparatus according to claim 1 , further comprising a bed on which the object is positioned.

21. The apparatus of claim 1 , further comprising:

a rotation apparatus configured to rotate a position of the X-ray source around the object; and

the controller is further configured to control the compensation filter based on the position of the X-ray.

22. The X-ray diagnosis apparatus according to claim 21 , wherein the controller comprises:

a memory configured to store data of an amount of the X-ray corresponding to the position of the X-ray source; and

a main controller configured to read the data from the memory based on the position of the X-ray.

23. The X-ray diagnosis apparatus according to claim 22 , wherein the memory is configured to store the data of the amount of the X-ray corresponding to a plurality of positions of the X-ray source.

24. The X-ray diagnosis apparatus according to claim 21 , further comprising an operation unit configured to set the amount of the X-ray on an X-ray fluoroscopic image.

25. The X-ray diagnosis apparatus according to claim 21 , further comprising a bed on which the object is positioned.

26. The apparatus of claim 1 , further comprising:

a diaphragm configured to restrict an irradiation range of the X-ray; and

means for controlling the diaphragm based on the position of the X-ray source in the first direction.

27. The apparatus of claim 1 , further comprising:

a diaphragm configured to restrict an irradiation range of the X-ray;

a rotation apparatus configured to rotate a position of the X-ray source around the object; and

means for controlling the diaphragm based on the position of the X-ray source.

28. A method for obtaining an X-ray image, comprising:
