Abstract
A sensor assembly that allows a sensor to be detachably mounted onto a fluoroscopic mount, such as a C-arm, is provided. The sensor assembly includes an electromagnetic sensor that is configured for outputting positional data relating to the fluoroscopic mount. The sensor includes a mount engaging element, and the sensor mount includes a sensor engaging element, both of which are configured to be removably mounted in an interference relationship with each other. The mount engaging element of the sensor can be a sensor housing, or alternatively, an element that is separate from the sensor housing. The sensor mount, which is composed of a non-ferromagnetic material, further includes a spacer for maintaining the sensor a prescribed distance from the ferromagnetic fluoroscopic mount, thereby minimizing any adverse ferromagnetic effects on the sensor.
