The aim of this work is to investigate localization and
tracking techniques to automatically select which
MR-visible markers are required to be visible on the MR
image by the robot control module. To unambiguously
distinguish the markers, each marker can be selectively
visible or invisible on the MR image for monitoring the
motion of the MR-compatible manipulators. The described
technique can be used for robust and fast tracking with
two-dimensional images or one-dimensional projections of
multiple markers on an interventional device, such as
the shaft of steerable catheters and the end-effectors
of MR-compatible manipulators.
