Abstract
A camera assembly for use in a MRI machine. The camera assembly includes a Faraday cage defining a shielded cavity and an optical path mount constructed of a highly stiff, dense, and non-electrically-conductive material in the shielded cavity. The camera imager and lens are mounted to the optical path mount. The camera assembly includes a capacitor-based power regulation circuit. The optical path mount is not subject to eddy currents because it is non-electrically-conductive. The capacitor-based power regulation circuit includes very little ferrous material and is within the shielded cavity, to reduce eddy currents. The resulting camera assembly reduces vibrations and shaking in the magnetic field environment of the MRI machine.
