The problem of positioning mobile C-arms, e.g. for down the beam techniques, as well as repositioning during surgical procedures currently
requires time, skill and additional radiation. The Camera-Augmented Mobile C-arm (CAMC) is able to speed up the procedure, simplify its
execution and reduce the necessary radiation. The C-arm is extended by a CCD camera. The CCD camera is attached to the C-arm such that it is virtually at the same location than the x-ray source. This is done by a double mirror construction. A two step calibration routine has be done only once at the moment the camera is attached. Extensions for a lightwight, but complete navigation system for pedile screw placement or implant positioning is currently under investigation.
