Abstract
An X-ray imaging apparatus includes: a C-arm formed in a C-shaped arc form, and being capable of sliding in an arc direction; an X-ray generator held on one end side of the C-arm; an X-ray detector held on the other end side of the C-arm while being opposed to the X-ray generator; and a first rotation axis which is fixed at a fixation portion to a ceiling portion of a room where the C-arm is installed, and which enables the C-arm to be rotated about an axial center of the first rotation axis, the axial center being a normal line extending in a vertical direction from the center of the fixation portion.

An X-ray imaging apparatus comprising:
- a C-arm formed in a C-shaped arc form, and being capable of sliding in an arc direction;
- an X-ray generator held on one end side of the C-arm;
- an X-ray detector held on the other end side of the C-arm while being opposed to the X-ray generator;
- and
- a first rotation axis which is fixed at a fixation portion to a ceiling portion of a room where the C-arm is installed, and which enables the C-arm to be rotated about an axial center of the first rotation axis, the axial center being a normal line extending in a vertical direction from the center of the fixation portion.
An X-ray imaging apparatus comprising:
- a first rotation axis fixed at a fixation portion to a ceiling portion and having as an axial center a normal line extending in a vertical direction from the center of the fixation portion;
- a holding body joined to the first rotation axis in a manner rotatable about the axial center of the first rotation axis;
- a long ceiling support arm joined to the holding body in a manner rotatable about the axial center of the first rotation axis, and extending in a direction horizontal to the ceiling portion;
- a sliding body joined to the ceiling support arm and being capable of sliding in a longitudinal direction of the ceiling support arm;
- a second rotation axis having a joint portion on an upper end side thereof joined to the sliding body, and having as an axial center a normal line extending in the vertical direction from the center of the joint portion of the second rotation axis;
- a long horizontal support arm including one end side joined to a lower end side of the second rotation axis, extending in a horizontal direction and being rotatable about the axial center of the second rotation axis;
- a third rotation axis having a joint portion of an upper end thereof joined to the other end side of the horizontal support arm in a longitudinal direction, and having as an axial center a normal line extending in the vertical direction from the center of the joint portion of the third rotation axis;
- a rotation axis housing portion joined to a lower end side of the third rotation axis;
- a horizontal rotation axis housed in the rotation axis housing portion and having a horizontal axial center being orthogonal to the axial centers;
- a holder portion held to be rotatable about the axial center of the horizontal rotation axis;
- a C-arm formed in a C-shaped arc form and held by the holder portion in a manner capable of sliding in an arc direction;
- an X-ray generator held on one end side of the C-arm;
- and
- an X-ray detector held on the other end side of the C-arm while being opposed to the X-ray generator.
