| MMSys: Motion Management System Recent advances in range imaging (RI) have enabled real-time acquisition of
dense and metric 3-D surface data. A variety of medical applications will
benefit from real-time RI in the future. The focus of this research project
is on the application of RI sensors to improve the accuracy, safety and
workflow of fractionated radiotherapy (RT). As the name implies, the
irradiation of the tumor is performed in multiple sessions according to a
treatment plan that is generated from an initial computed tomography (CT)
scan. In order to ensure an accurate adjustment of the external beam, the
oncological patient must be aligned to the reference position of the
planning CT before each treatment session. In this project, we develop a
surface-based method for patient positioning that relies on multi-modal
RI/CT data registration. In comparison to existing alignment strategies, our
approach is accurate, marker-less, non-invasive, contactless and does avoid
additional radiation exposure. Real-time motion management is another
promising application of RI in RT. We develop a motion management system for
acquisition and classification of a multi-dimensional volumetric respiratory
signal. The system monitors specific anatomical regions of the upper part of
the body and determines the instantaneous phase within the respiration
cycle.
