First Claim
Patent Images
1. An X-ray imaging system, comprising:
- an X-ray radiation source;
an X-ray detector;
a C-arm having the X-ray radiation source disposed on a first end and the X-ray detector disposed on a second end opposite the first end;
a C-arm rotation device configured to enable the C-arm to rotate in an orbital direction relative to the C-arm rotation device; and
an orbital clutch and brake assembly coupled to the C-arm rotation device, wherein the orbital clutch and brake assembly is spring loaded into the C-arm and configured to apply both a drag force and a braking force on the C-arm that is consistent along the C-arm in the orbital direction regardless of variations in a cross-sectional profile of the C-arm in the orbital direction.

Abstract
A device is provided. The device includes an orbital clutch and brake assembly configured to couple to a C-arm rotation device that enables the C-arm to rotate in an orbital direction relative to the C-arm rotation device. The orbital clutch and brake assembly includes a housing, a roller, and a brake pad. The roller and brake pad are disposed within the housing. The brake pad is configured to directly contact the roller and to not contact the C-arm when the orbital clutch and brake assembly applies a braking force to the C-arm.
