Abstract
A C-arm apparatus. An X-ray imaging system is coupled to a C-arm, including an X-ray source and an image receptor mounted upon opposing locations, respectively on the C-arm. The C-arm is mass balanced about its axis of orbital rotation and is pivotally coupled to an articulating arm assembly supported upon a wheeled support base. The mass balance enables repositioning of the X-ray imaging system between an anterior-posterior view and an orthogonal lateral view with a single, orbital movement of the C-arm which also causes the views to define an imaging isocenter. The C-arm is preferably miniaturized to an approximate diameter of twenty-eight inches with a source-to-image distance of approximately fourteen inches.
