Tracking and Navigation of instruments / systems and small imaging systems is performed using commercially available systems based on infrared cameras or electromagnetic fields. Both have advantages and drawbacks for use with handheld gammacameras or ultrasound probes. Main disadvantage is that you require a separate system.

It would be advantageous to have a small system ADD-ON that is directly attached to the device that is being tracked.

Based on a patent application and some work that was performed by the Max-Planck-Society in Leipzig (EMOTRAC - motion tracking of head movement with a small camera system) it is proposed to use one to three small cameras in a separate samll system to be attached to the device to be tracked. These cameras track the motion of the device with respect to one to three markers (barcode, geometric forms, ...) that are attached to the human body.

The project work expects that a small, rudimentary prototype is build including the tracking software and data sets that are required for accurate tracking and image stitching or image fusion. Accuracy of 1mm in all three dimensions is required in a real-time setup.

Expenses are being paid by the work group of Michael Friebe and a small “work fee” can be negotiated! Please contact Michael Friebe ( or Philipp Matthies (
