Interactive Visualization for Image Guided Medialization Laryngoplasty

Surgical procedures require the physician to use preoperative and intra-operative information for deciding the optimal course of action to be taken on the patient. Medical visualization techniques are used to ‘guide’ the surgeon during the procedure to improve accuracy. We are presenting a visualization approach for image guided medialization laryngoplasty. A brief background is provided to describe the goal of the surgery. The problems associated with visualizing the available information and the proposed solutions are discussed. Our solutions aim to improve the mental registration of the virtual and real worlds by adding visual cues to the visualization and by interactive volume visualization and exploration schemes. Our approach displays medical images, image/video feeds and computer simulations in a single view. Methods were implemented on the GPU to achieve real time frame rates. Optical and electromagnetic tracking methods were used for direct interaction on the patient.
