Malignant tumors are significantly stiffer and more immobile than surrounding healthy tissue. Hard calcifications in vessels occur due to arteriosclerosis. The problem is, that such information is usually not available or can only be obtained by manual palpation, which is subjective and limited in sensitivity. It requires intuitive assessment and does not allow quantitative documentation. Unfortunately, none of the established medical imaging equipment such as magnetic resonance imaging (MRI) or X-ray computed tomography (CT) can provide direct measure of tissue elasticity. On the one hand a suitable sensor is required for quantitative measurement of mechanical tissue properties. On the other hand there is also some need for a realistic haptic display of such tissue properties. Suitable actuator arrays with high spatial resolution acting in real time are required. A haptic sensor actuator system is presented in this paper including a sensitive sensor part and an actuator array for different applications. The mechanical consistency of an object is to be locally specified using a sensor system and represented perceptibly in a remote position on an actuator system for the user. The sensor system uses ultrasound (US) elastography, whereas the actuator array is based on electrorheological (ER) fluids.}, language = {en} } @inproceedings{KhaledReichlingBruhnsetal., author = {Khaled, W. and Reichling, S. and Bruhns, Otto T. and Monkman, Gareth J. and Egersd{\"o}rfer, Stefan and Baumann, Michael and B{\"o}se, Holger and Klein, Dagmar and Freimuth, Herbert and Tunayar, A. and Lorenz, A. and Pessavento, A. and Ermert, Helmut}, title = {Palpation imaging using a haptic system for virtual reality applications in medicine}, series = {Perspective in image-guided surgery : proceedings of the Scientific Workshop on Medical Robotics, Navigation, and Visualization : RheinAhrCampus Remagen, Germany, 11-12 March}, booktitle = {Perspective in image-guided surgery : proceedings of the Scientific Workshop on Medical Robotics, Navigation, and Visualization : RheinAhrCampus Remagen, Germany, 11-12 March}, publisher = {World Scientific Publ.}, address = {Singapore}, pages = {407 -- 414}, language = {en} } @inproceedings{KhaledReichlingBruhnsetal., author = {Khaled, W. and Reichling, S. and Bruhns, Otto T. and Monkman, Gareth J. and Egersd{\"o}rfer, Stefan and Baumann, Michael and B{\"o}se, Holger and Klein, Dagmar and Freimuth, Herbert and Tunayar, A. and Lorenz, A. and Pessavento, A. and Ermert, Helmut}, title = {Palpation Imaging using a Haptic System for Virtual Reality Applications in Medicine}, series = {Proceedings of the 12th Annual Medicine Meets Virtual Reality Conference: - Building a Better You: The Next Tools for Medical Education, Diagnosis, and Care. - Medicine Meets Virtual Reality (MMVR) - Newport Beach (California, USA). 2004}, booktitle = {Proceedings of the 12th Annual Medicine Meets Virtual Reality Conference: - Building a Better You: The Next Tools for Medical Education, Diagnosis, and Care. - Medicine Meets Virtual Reality (MMVR) - Newport Beach (California, USA). 2004}, language = {en} } @article{KhaledBruhnsReichlingetal., author = {Khaled, W. and Bruhns, Otto T. and Reichling, S. and B{\"o}se, Holger and Baumann, Michael and Monkman, Gareth J. and Egersd{\"o}rfer, Stefan and Meier, Alexander and Klein, Dagmar and Freimuth, Herbert and Ermert, Helmut}, title = {A haptic system for virtual reality applications based on ultrasound elastography and electrorheological fluids}, series = {Acoustical Imaging}, journal = {Acoustical Imaging}, number = {27}, publisher = {Kluver Academic}, address = {Dordrecht \& New York}, doi = {10.1007/978-1-4020-2402-3_85}, pages = {667 -- 675}, language = {en} } @inproceedings{KhaledReichlingBruhnsetal., author = {Khaled, W. and Reichling, S. and Bruhns, Otto T. and Ermert, Helmut and Monkman, Gareth J. and Egersd{\"o}rfer, Stefan and Baumann, Michael and B{\"o}se, Holger and Freimuth, Herbert and Tunayar, A.}, title = {Palpation imaging using a haptic sensor actuator system for medical applications}, series = {Actuator 2004 : 9th International Conference on New Actuators \& 3rd International Exhibition on Smart Actuators and Drive Systems, 14-16 June 2004, Bremen, Germany}, booktitle = {Actuator 2004 : 9th International Conference on New Actuators \& 3rd International Exhibition on Smart Actuators and Drive Systems, 14-16 June 2004, Bremen, Germany}, publisher = {HVG Hanseatische Veranstaltungs-GmbH}, address = {Bremen}, pages = {379 -- 382}, language = {en} }
