Summary:
- The recent evolutions in the radiotherapy treatment of tumors call for the design of new assistance tools allowing to control both the patient positioning relatively to a reference position, but also that of the robots in charge of remote tasks pertaining to the displacement of the patient or the equipment associated to the treatment session. In parallel, the progress of treatments go together with longer and longer remission periods, but also, unfortunately, with the recurrence of treatments for other cancers, induced or not. In such cases, there is an ever growing need to superimpose the image data of the same patient at two different moments of the long-term evolution of the disease.
- This PhD research aims at bringing answers on the two previous points, with the help of :
- models for the treatment room and its equipments (robots or not),
- tools for the control of quality of the robot devices (in particular collision detections / prevision),
- tools for the quantification of precision at all supervision levels (imaging, robotics, patient, ...),
- tools for the mixing of video acquisition (far vision, close vision) and of the multiple medical image modalities available,
- tools for the mixing of video acquisition (far vision, close vision) and of the multiple medical image modalities available,
- tools for supervising (weak and strong) movements of the patient and the dispacements of robotized equipment, and possibly of the staff (off beam),
- and by also providing morphometric data on breathing to other modules developed at LIRIS for the design of a biomechanical model for respiration.
