Abstract
A system and method for compensating for torque reaction forces in a medical apparatus is disclosed. The system may include a rotary element which rotates about an axis. A contra-rotating flywheel may be driven to rotate about the axis relative to the rotary element, wherein the flywheel is free to rotate and is accelerated and decelerated by a driver which is fixed to the rotary element. Contra-rotation of the flywheel may compensate for torque reaction forces when the rotary element is accelerated or decelerated.
Claims20
A system for use with a medical apparatus having a rotary element which rotates about an axis, the system comprising:
- a contra-rotating flywheel which is driven to rotate about the axis relative to the rotary element, wherein the flywheel is free to rotate and is accelerated and decelerated by a driver which is fixed to the rotary element.
A method of compensating for torque reaction forces in a medical apparatus comprising a rotary element which rotates around an axis, the method comprising:
- driving a contra-rotating flywheel relative to the rotary element, wherein the flywheel rotates around the axis in the opposite direction of the rotary element, and wherein the flywheel is free to rotate and is accelerated and decelerated by a driver which is fixed to the rotary element.
