Haptic rendering of medical image data for surgical rehearsal
Abstract/Contents
- Abstract
- This thesis investigates the problem of haptic rendering of medical image data for applications in surgical simulation. Surgical rehearsal is an emerging concept where an immersive simulation environment is created from patient-specific, pre-operative image data. Surgeons and trainees would then have an opportunity to rehearse procedures before operating on that patient. Patient-specific surgical simulation requires not only real-time visualization, but also a means of touching and manipulating a virtual model of that patient's unique anatomy. Haptic devices provide a means of achieving touch-enabled interaction. Thus computer haptics, the discipline concerned with generating and rendering haptic stimuli, is integral to high-fidelity surgical rehearsal. Haptic rendering algorithms to enable force-feedback interaction with pre-operative image data are presented in this work. These methods enabled the creation of virtual surgical environments for temporal bone surgery and for endoscopic sinus surgery. The systems were validated by comparing the experience in the simulation environment with observations from the actual procedure. Findings in the virtual surgical environment bore a high resemblance to images captured from intra-operative video of the same patients, indicating the predictive value of the simulation.
