摘要： A mechanically adjustable brake for use with a C-arm x-ray apparatus is generally comprised of a brake handle and an eccentric shaft support which, when rotated using the handle, actuates a cam and presses a brake pad into the C-arm. Movement of the C-arm is thus restricted when the brake is applied. The brake mechanism specifically includes a brake handle, a brake shaft, a cam mounted on the brake shaft, a plunger having a first end engaged with the cam and a second end having a brake. The brake handle is used to rotate the brake shaft and the cam, the cam pushes down on the plunger and the brake engages the C-arm. The brake mechanism further comprises a plunger support, a spring that is compressed when the brake is actuated and is decompressed when the brake is released thus permitting movement of the C-arm. The brake shaft is connected to the brake handle using an eccentric shaft support. The shaft support has an inner aperture having a center offset from the center of the outer perimeter and a plurality of parallel grooves in the outer perimeter of the shaft support that permit removal and advancement of the eccentric shaft support.

摘要： An X-ray tube device is rotated to a projected portion in a subject by a rotating mechanism for the X-ray tube device according to an operation for an oblique fluoroscopy. A CPU recognizes information about a rotating angle and rotation speed, and a stand for the X-ray tube is moved along a longitudinal direction of a top plate by a driving mechanism for the stand according to the information. An X-ray image detector disposed under the top plate is moved in a direction opposite to the movement of the stand to a corresponding position of the X-ray tube device by a driving mechanism for the X-ray image detector. The X-ray tube device, the projected portion in the subject and the X-ray image detector are always arranged in a straight line by the CPU and the independent driving mechanisms. A tomography may also be carried out by moving continuously the X-ray tube device and the X-ray image detector parallel to the top plate in the opposite directions.

摘要： A virtual C-arm support system 40 is used in a radiographic imaging apparatus of the type including an x-ray source 44 and an x-ray detector 48. The support system includes a first positioning system 42 operatively connected to the x-ray source for selectively positioning the x-ray source in a range of first orientations 120, 140, 170 relative to the examination region E. A second positioning system 46 is operatively connected to the x-ray detector 48 for selectively positioning the x-ray detector in a range of second orientations 122, 142, 172 relative to the examination region E. A control unit 60 is in operative command of at least one of the first and second positioning systems to maintain a predetermined spatial relationship between the x-ray source and the detector for each of the ranges of the first and second orientations relative to the examination region. In a second embodiment, the control unit is in operative command of only the first positioning system, the second positioning system being manually movable. The control unit maintains a predetermined spatial relationship between the x-ray source and detector by moving the x-ray source in response to manual movement of the x-ray detector for each of the ranges of first and second orientations of the source and detector relative to the examination region.

摘要： A device for moving an X-ray apparatus embodied in the form of a C-bow (9) in a controlled manner, the C-bow (9) being mounted on a pedestal (31) provided with motor-driven rollers (3) controllable in their direction of travel in such a way that it is displaceable in parallel in relation to at least two axes (18;19) and rotatable relative to three axes (18; 19, 21), each movement of the C-bow (9) with respect to a coordinate system (29) which is stationary relative to the room being carried out via controllable drive devices (6;7;37;38). These drive devices (6; 7; 37; 38) are controlled either by means of a control device (39;48) or via a computer (23), said control device being operated either via a sterile control console or by voice control. Any positions and projections of the C-bow (9) that have once been adjusted may be stored in the computer (23), so that a desired position and projection may be reproduced again. If the C-bow 9 is combined with a surgical navigation system which comprises a position detector (27), it is possible, by measuring a reference base that is applied to a patient (12) and is provided with optical markers (28), to consider changes in the position of the patient (12) in such a way that an adjusted position and projection of the C-bow (9) can be reproduced after the patient (12) has changed position.
