An assembly of devices that comprise a portable (moved from one location to another, and easily reassembled) general-purpose diagnostic fluoroscopic x-ray system that uses real-time analogue or analogue-to-digital techniques for image capture, display and manipulation used in a variety of general-purpose applications requiring real-time fluoroscopic imaging. It includes spot-film capabilities in addition to the fluoroscopic features and is intended to optimize the capability of users to visually and quantitatively evaluate the anatomy and physiological function of various targeted body areas in real-time. It is frequently used in conjunction with an ingested/injected x-ray contrast medium.
