碩士 === 中原大學 === 資訊工程研究所 === 93 === A major application of virtual reality in medicine is to construct 3D human tissue model. We use computed tomography to build the volume model of the bone tissue, and the simulating system based by volume rendering virtual reality can be used by doctors to observe bone tissues three-dimensionally, and interact with the virtual bone tissue, to make diagnosis accurate. Doctors are also able to simulate surgical operation in the volume model, to design a surgical plan and to testify it, or to train doctors or students without clinical experience. This study constructs a force feedback system under previous surgical simulating system. With the hardware device to provide force feedback mechanism, we simulate a drill scalpel in the volume model. This simulated scalpel can travel in volume space, and interact with volume model. When scalpel touched bone tissue, it send a force back to user’s hand like there is an object. And when user activate the drill and simulate tunneling operate on bone tissue, user can feel like a real force feedback like a real drill will do, and can see the changes about model. By adding sense of touch, we provide an interact that can make the simulating system more factually.
