Abstract
A C-arm system is disclosed herein. The C-arm system includes a support assembly, and a C-extension connected to the support assembly. The C-extension is selectively rotatable relative to the support assembly in both a clockwise and a counterclockwise direction. The C-arm system also includes a C-gantry connected to the C-extension. The C-gantry is adapted to retain an x-ray source and an x-ray detector. The C-gantry is selectively rotatable relative to the C-extension in both a clockwise and a counterclockwise direction. The C-extension is operable to extend the range of C-gantry rotation in both clockwise and counter clockwise directions. A corresponding method for operating a C-arm system is also provided.
Claims19
A C-arm system comprising:
- a support assembly;
- a C-extension connected to the support assembly, said C-extension being selectively rotatable relative to the support assembly in both a clockwise and a counterclockwise direction;
- and
- a C-gantry connected to the C-extension, said C-gantry adapted to retain an x-ray source and an x-ray detector, said C-gantry being selectively rotatable relative to the C-extension in both a clockwise and a counterclockwise direction;
- wherein the C-extension is operable to extend the range of C-gantry rotation in both a clockwise direction and a counter clockwise direction.
A C-arm system comprising:
- a support assembly defining a support assembly groove;
- a C-extension having a first ridge and a second ridge, said C-extension connected to the support assembly such that the first ridge is disposed at least partially within the support assembly groove, said C-extension being selectively rotatable relative to the support assembly in both a clockwise and a counterclockwise direction;
- a C-gantry defining a gantry groove, said C-gantry connected to the C-extension such that the second ridge is disposed at least partially within the gantry groove, said C-gantry adapted to retain an x-ray source and an x-ray detector, said C-gantry being selectively rotatable relative to the C-extension in both a clockwise and a counterclockwise direction;
- a first motor operatively connected to the C-extension;
- a second motor operatively connected to the C-gantry;
- and
- a controller operatively connected to the first motor and the second motor such that C-extension rotation and C-gantry rotation can be independently induced in a selectable manner;
- wherein the C-extension is operable to extend the range of C-gantry rotation in both a clockwise direction and a counter clockwise direction.
A method for operating a C-arm system comprising:
- providing a C-extension that is selectively rotatable in a clockwise or counter clockwise direction;
- providing a C-gantry that is connected to the C-extension, said C-gantry being selectively rotatable in a clockwise or counter clockwise direction
- controlling a first motor operatively connected to the C-extension in order to induce a selectable amount of C-extension rotation;
- and
- controlling a second motor operatively connected to the C-gantry in order to induce a selectable amount of C-gantry rotation;
- wherein independently controlling the first motor and the second motor increases the C-gantry range of rotation in both the clockwise direction and the counter clockwise direction.
