ABSTRACT:
A compact, lightweight, portable, versatile and modular field x-ray system is disclosed. A base member is provided and supports an x-ray table. Two vertical masts are also coupled to the base, for movement alongside the table in a direction parallel to its longitudinal dimension. The masts move independently of one another but can also be linked together for movement in unison. A tube head is attached to one mast by articulated structure, including a series of offset arms, which affords the tube head 6 degrees of freedom of movement, both above and below the x-ray table. A spot film device is movable coupled to the second mast. The second mast and spot film device are manually removable from the remainder of the system for operation in radiographic only mode. When the masts are linked together, the tube head, because of the offsetting nature of the coupling arms, can be precisely vertically aligned with respect to the spot film device, and the entire assembly of masts, tube head and spot film device can be moved in unison for fluoroscopic panning.
