摘要： 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 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.

摘要： A universal radiographic/fluoroscopic room includes a digital imaging platform adapted to occupy operating and non-operating positions. A park function automatically moves the digital imaging platform between the operating and non-operating positions without requiring operator effort. The digital imaging platform has local and remote control panels having substantially duplicate functions. The remote control panel allows the operator to control operation of the digital imaging platform from a location shielded from X-ray exposure. Methods and apparatus are provided to ensure safe, predictable, and consistent operation from all control panels. 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.

摘要： A universal radiographic apparatus that allows an operator to select between conventional radiographic mode and linear tomographic mode. In conventional radiographic mode of operation, several automatic modes are provided. An x-ray tube mounted to a tube crane positioned above an elevating table can be accurately controlled in longitudinal and vertical movement, as well as in x-ray tube angulation. In linear tomographic mode, a table bucky is moved laterally in opposition to movement of the tube crane, with angulation keeping the tube aimed at the bucky. In conventional radiographic mode, the system supports an auto bucky mode, where the table bucky automatically tracks tubecrane motion, or an auto table mode, where the tube crane tracks table vertical motion to maintain a fixed SID. In an auto wall mode, the tube crane tracks vertical movement of an associated wall bucky.
