P2 Optical Tracking in Medical Physics

Optical tracking systems use infrared light to determine the position of a target relying on multiple stereoscopic cameras. The multiple views of the same scene can be used to reconstruct accurate 3D locations of each object in the scene. The ability to track the location of a single object by itself is not sufficient to track the location of a target (point) inside the patient. Such a goal can be achieved by correlating the position of external marker to the 3D motion of internal targets, relying on dedicated imaging data. In this way, optical tracking systems can be used to provide stereotactic localization, allowing quasi real-time measurements to implement motion management strategies.

The laboratory course will focus on calibration and use of an optical tracking device, to measure motion via stray markers or characterize objects using an optical probe. Integration of optical motion measurements and imaging data will be also explored by master students participant, relying on an MRI compatible breathing motion phantom.
The laboratory course is aimed at bachelor and master students. For bachelor students, the sections on the breathing motion phantom (section 4, 5.4 and 6.4) should be ignored in the manual. We strongly suggest that students seeking the LMU Medical Physics Master Certificate follow the laboratory course.

Scheduling:
1) Lab course date (both 1st kolloquium and experiment)
2) 2nd kolloquium

For both 1) and 2) please contact the supervisor below to set a date.

Contact persons:

Prof. Dr. Marco Riboldi

Please read the manual carefully prior to your lab course
