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 practical use of optical devices, including both localization of reflective markers and surface-based measurements. The activities will include calibration verification and repeated phantom measurements using different devices. Interactive positioning of the phantom based on surface information will be also carried out, mimicking surface based patient setup in external beam radiotherapy.

The laboratory course is aimed at bachelor and master students. 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
