    摘要： 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.
