Kurzbeschreibung (Abstract)

Conventional navigation during catheterizations is done by direct manipulation of a handle at the proximal end of the guide wire. With the aid of x-ray imaging the corresponding movement of the guide wire’s tip in the patient’s vascular system can be monitored. Other human senses are not involved into the procedure and so cardiologist’s perception is reduced while navigating through the blood vessels. Within the HapCath - project (Institute for Electromechanical Systems, TU Darmstadt) an assistive system for interventional catheterizations has been developed. It provides a haptic feedback by measuring the contact forces at the guide wire tip and feeding them back onto the proximal end of the guide wire to improve the tactile feedback. A further improvement of the assistive system could be generated by involving the audible sense as well. As perception of the cardiologist during catheterisation can be improved, procedure duration and x-ray exposure dose can be reduced. Therefore the aim of this work is to provide an additional acoustic signal corresponding to the contact forces at the guide wire tip to provide a multimodal feedback to the cardiologist. The blood vessels surface is characterized only by the dynamic parts of the force signal. Therefore several signal modu-lation procedures were considered. Aim of this paper is the implementation of these procedures into an acoustic demon-strator system. Further work will be testing the different signal processing algorithms, selecting the most appropriate one and implementing it into the HapCath - system.
