ABSTRACT The graphical 3D-simulation system COSIMIR has a wide range of application areas, including robotics, space, and forest applications. Now, the positioning of patients in radiotherapy extends COSIMIR's usage to the medical field. After a brief overview of COSIMIR including some recent examples of applications the talk will give a short introduction to radiotherapy. An analysis of the system requirements shows the way to the system design. The proposed system architecture registers 2D-x-rays and 3D-CT data. The registration concept is based on the calculation of digitally reconstructed radiographs (DRRs) and uses an innovative concept to quickly generate high quality DRRs. Finally, the talk will finish with first results based on synthetic and real x-rays of a human skull phantom. SPEAKER BIO Frank Heinze studied Electrical Engineering at the University of Paderborn, Germany and at the University of Illinois at Urbana/Champaign. He graduated from the University of Paderborn in 1996. Since 1996 he is a postgraduate research assistant at the Institute of Robotics Research in Dortmund, Germany. He is responsible for the development of the robot programming software COSIROP and he runs a joint project with the clinic and polyclinic of radiotherapy at the University of Essen. His research interests include medical robotics, 2D/3D registration, graphical 3D-simulation and user-friendly operation of industrial robots. Frank Heinz |
