G-arm X-ray imaging apparatus
An X-ray imaging apparatus is provided having advantages of both C-shaped, G-shaped, and ring-shaped arm configurations. The device consists of a gantry that supports X-ray imaging machinery. The gantry is formed to allow two bi-planar X-rays to be taken simultaneously or without movement of the equipment and/or patient. The gantry is adjustable to change angles of the X-ray imaging machinery. Further, in some embodiments, the X-ray receptor portion of the X-ray imaging machinery may be positioned on retractable and extendable arms, allowing the apparatus to have a larger access opening when not in operation, but to still provide bi-planar X-ray ability when in operation.

2. The bi-planar X-ray apparatus of claim 1 wherein the support gantry forms an arc.
3. The bi-planar X-ray apparatus of claim 2 wherein the support gantry and first and second X-ray receptors form a C-shaped arm when the X-ray receptors are in the retracted position, and form a G-shaped arm when the X-ray receptors are in the extended position.
4. The bi-planar X-ray apparatus of claim 1 wherein the gantry is attached to a gantry support, the gantry movable with respect to the gantry support to allow an orbital motion of the first and second imaging chains.
5. The bi-planar X-ray apparatus of claim 4 wherein the gantry support is attached to a cross arm, the cross arm supporting the gantry support and gantry at a proximal end, the cross arm being capable of adjustment in a direction along its length.
6. The bi-planar X-ray apparatus of claim 5 wherein the cross arm has an up-down column perpendicularly attached adjacent to a distal end, the up-down column allowing pivoting motion of the cross arm as well as allowing the cross arm to move upwardly and downwardly.
7. The bi-planar X-ray apparatus of claim 6 wherein the up-down column is attached to a wheeled cart.
8. The bi-planar X-ray apparatus of claim 1 further comprising a motor to move at least one of the first and second X-ray receptors between the extended position and the retracted position.
9. The bi-planar X-ray apparatus of claim 1 wherein the first imaging chain and second imaging chain are arranged to perpendicularly.
10. The bi-planar X-ray apparatus of claim 1 wherein the first arm is slidable within the gantry.
11. The bi-planar X-ray apparatus of claim 1 wherein the first arm is slidable along an external edge of the gantry.
12. The bi-planar X-ray apparatus of claim 1 wherein the first and second imaging chains are attached to a side surface of the gantry.
13. The bi-planar X-ray apparatus of claim 1 wherein the first and second imaging chains are attached along a central plane of the gantry.
14. The bi-planar X-ray apparatus of claim 2 wherein the first X-ray receptor is adjustable in a radial direction of the arc shaped gantry.
15. The bi-planar X-ray apparatus of claim 14 wherein the second X-ray receptor is adjustable in the radial direction of the arc shaped gantry.
16. The bi-planar X-ray apparatus of claim 1 further comprising a computerized control system, the computerized control system in communication with the first and second imaging chains and capable of controlling operation of each of the first and second imaging chains.
17. The bi-planar X-ray apparatus of claim 16 wherein the computerized control system is configured to allow simultaneous operation of the first and second imaging chains.
18. The bi-planar X-ray apparatus of claim 16 wherein the computerized control system is configured to allow operation of one of the first and second imaging chains at a time.
19. The bi-planar X-ray apparatus of claim 1 further comprising a display capable of displaying an image produced by one of the first imaging chain and the second imaging chain.
