Virtual Rehearsal of Temporal Bone SurgeryOur virtual surgical environment constructs interactive anatomical models from patient-specific medical image data. Images visually and haptically rendered to reproduce the look and feel of surgery. Evaluation of the system demonstrated strong correlations between virtual and real anatomy. |

Haptic Rendering of Deformable TissuesThis project demonstrates haptic rendering of deformable tissue within medical images. We developed a proxy-based rendering algorthm that operates on volumetric data which allows for real-time deformation, and a process to generate a mesh from image data to drive a deformable body simulation. |

Endoscopic Sinus Surgery SimulationEndoscopic sinus surgery is a challenging procedure that can benefit from surgical rehearsal. We designed a simulator capable of constructing a virtual 3D model of the patient from a clinical CT scan. Surgically relevant anatomy seen during simulation can predict what may be encountered in the OR. |

Six-DOF Haptic Rendering of Volumetric DataWe developed a method for 6-DOF haptic rendering of isosurface geometry embedded within sampled volume data. The algorithm uses a quasi-static formulation of motion constrained by multiple contacts to simulate interaction between a virtual instrument and volumetric isosurfaces. |
