In general, the system according to this invention includes controls for orbital and cross-arm motorized motion into one or more handles. The handle is configured to provide 'motor-assist' in the direction along which force is applied. In one example, the control handle is affixed to the distal end of an image receptor. The users' natural inclination to apply force in the direction in which the detector is required to move is translated into one or more compliant motor motions much similar to a remote joystick control. In another example, an actuator is integrated to the mounting of the existing handle.
FIELD OF THE INVENTION
 This invention relates generally, to C-arm positioning systems, and more particularly to, a motor assisted C-arm positioning system for medical imaging equipments.
BACKGROUND OF THE INVENTION
 Mobile Fluoroscopic ‘C-arms’ are widely used in hospitals, clinics and physician offices for a wide range of clinical applications. Most C-arm mechanical designs provide quick and versatile positioning of the gantry by means of brakes, counterbalances and gas springs.
 A known system for C-arm positioning includes motorization of C-arm motions that have previously required manual positioning. Motorization is controlled from a remote panel that is designed to attach to the operating table. Although manual manipulation of the C-arm is still possible, linkage to the motors creates resistance and inhibits easy manual positioning. Further, these known systems includes the following problems, namely (i) Control access – motorization of orbital and ‘cross-arm’ rotation can only be controlled from a single remote tableside control panel, and (ii) normal manual positioning of these motions by grasping the handles located at the extreme ends of the C-arm assembly is difficult due to the motor links.
