We introduce a method to track the 3D curve of a moving active interventional device with a loopless-coil design. The goal is to collect small amounts of tracking data in between the data collection required for the reconstruction of multiple slices in the real-time display. The tracking data consists of two highly undersampled projection images of the device. We are able to achieve a greater data reduction than all previous methods by using slice-direction-dephased projection images of the device and optimal in-plane rotation.
