Title Proper : A HYBRID COLLISION DETECTION METHOD FOR VIRTUAL LAPAROSCOPIC SURGERY
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : With advances in computing power and graphical capabilities, it is possible todevelop a Virtual Reality (VR) - based realistic trainer for surgical training. Laparoscopicsurgery is taking over open surgery techniques due to its reduced morbidity and recoverytime. Collision detection has always been a challenging field of research in VR- basedapplications. In particular, surgical simulations involving collisions between complexdeformable objects require intense computation when compared to those between non-deformable objects. It is essential to assist the medical surgeon with visual realism byproviding accurate collision points in real-time. This research work addresses the problemof detecting collisions between a deformable mesh and the organs over which it needs tobe placed. The approach presented, is generic and can also be employed to other kinds ofcollision queries. Though, various collision detection methods have been proposed in thepast, they have not proven suitable for real-time speeds during the mesh placement taskin Laparoscopic inguinal hernia surgery. We have therefore developed a hybrid approach............-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
