Title

Clinical workflow optimized calibration-method for stereo-optical tracking in MRI

Title Supplement
Abstract
Abstract
Though motion tracking for head motion compensation in MRI has been a research topic for some time [1-4], literature is not giving much attention to the calibration of such systems. We present a method to calibrate the coordinate systems of a stereo-optical camera setup mounted to the MRI head coil and show that, though using a simple setup and visible light [1], it is possible to achieve a sub-millimeter tracking precision.
