Abstract

There are provided a radiation generating apparatus and a radiation imaging apparatus that have excellent transportability. The radiation generating apparatus and radiation imaging apparatus include a radiation generating unit configured to generate radiation, an arm configured to support the radiation generating unit, and a support pillar configured to support the arm and rotate the arm, wherein the support pillar has a housing portion that has a space for housing at least a part of the radiation generating unit.

Claims

1. A radiation generating apparatus comprising:

a radiation generating unit configured to generate radiation;

an arm configured to support the radiation generating unit; and

a support pillar configured to support the arm and rotate the arm,

wherein the support pillar has a housing portion that has a space for housing at least a part of the radiation generating unit.

2. The radiation generating apparatus according to claim 1, wherein the support pillar has an arm housing portion that has a space for housing at least a part of the arm.

3. The radiation generating apparatus according to claim 1, wherein the arm is configured to rotate around an upper end of the support pillar.

4. The radiation generating apparatus according to claim 1, wherein the support pillar is configured using a radiation shielding member.

5. The radiation generating apparatus according to claim 1, wherein an inner face of the housing portion is covered with a radiation shielding member.

6. The radiation generating apparatus according to claim 4, wherein the radiation shielding member is any one of a lead panel and a tungsten sheet.

7. The radiation generating apparatus according to claim 1, wherein, in a state in which an aperture portion of the radiation generating unit is facing the support pillar, the radiation generating unit is housed in the housing portion.

8. The radiation generating apparatus according to claim 1, wherein, in a state in which an aperture portion of the radiation generating unit is facing in a floor direction, the radiation generating unit is housed in the housing portion.

9. The radiation generating apparatus according to claim 1, further comprising a support pedestal configured to support the support pillar, wherein the support pedestal is detachable from the support pillar.

10. The radiation generating apparatus according to claim 1, further comprising a lock mechanism configured to lock rotation of the radiation generating unit when the radiation generating unit is housed in the housing portion.

11. The radiation generating apparatus according to claim 1, further comprising a cover configured to cover the radiation generating unit housed in the housing portion.

12. The radiation generating apparatus according to claim 1, further comprising a movable portion configured to move along a floor with the radiation generating unit.

13. A radiation imaging apparatus comprising the radiation generating apparatus according to claim 1, a radiation detection apparatus configured to detect radiation that has passed through a subject, and a display device configured to display an image generated based on detected data.
