ABSTRACT:
A universal radiographic/fluoroscopic "room" is constructed according to the present invention by combining a versatile group of X-ray examination system components, electrical and mechanical drive components, and sensing components, under the supervision of a flexible control system, to form a universal diagnostic medical imaging system capable of performing radiographic, fluoroscopic, tomographic, and stepped examinations in several different operator-selectable configurations. The operator selects any available operating mode, including auto-bucky, auto-wall, auto-table, auto-table/wall, servo-tomo, conventional stepping, stepped-digital, auto-step, and auto-step-center modes, using a control panel. The control system automatically determines which system components are required to perform that type of examination, moves the components into operational or storage positions as required, and prepares each component for operation. The operator need not manually reconfigure the equipment. In "stepped-digital" modes useful for peripheral angiography, an under-table X-ray tube and over-table image intensifier execute a series of radiographic exposures at preselected locations. The digital imaging platform is moved while the patient remains stationary. This reduces motion artifacts. For each step, a test fluoroscopic exposure is performed under automatic brightness control to determine an optimum technique. The technique so determined is converted for use in a subsequent radiographic exposure. The operator observes the flow of the contrast medium during the test fluoroscopic exposure and commands the radiographic exposure when the contrast medium arrives at the desired position in the image. Alternatively, the control system may detect the presence of the contrast medium in the image by comparing a change in image contrast with a previously observed threshold change.
