C-ARM X-RAY MACHINE WITH COUNTERBALANCE

摘要

A C-arm X-ray machine includes a C-arm that is rotatable about an orbital axis running perpendicular to a C-arm plane. The C-arm includes an X-ray source and an X-ray detector. An overall center of gravity of the C-arm, the X-ray source, and the X-ray detector exerts a first torque on the C-arm. A mass motionally coupled to the C-arm via a rotatable contour disk produces a second torque compensating the first torque.
