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.
