Tissue motion during
MR guided interventional procedures leads to the desire to perform simultaneous
high speed tracking of the surgical instrument and imaging. In this work, a novel
approach for concurrent tracking and imaging, based on an inertial measurement
unit (IMU) and technology from plane/missile
tracking, is presented. While
using infrequent position updates for the IMU (that could be provided by MR
tracking), we have showed fast tracking (166Hz) of the IMU sensor with ~2mm rms
error.
