C-arm x-ray apparatus for increased overscan

A C-arm x-ray machine includes a compact yoke and a support arm interposed between the yoke and the support base to reduce overall length of the machine and to increase overscan. The support arm is designed to lower the axis of rotation such that the axis of rotation nearly coincides with the center of gravity of the C-arm. The compact yoke is designed with a thin pivot point and includes a steel sleeve to enclose a pin situated at the first end of the yoke. The steel sleeve is required to strengthen the yoke at the critical load bearing area near the first end of the yoke.
