Apart from the applications in surgical navigations, virtual surgery has become a new feasible method for training young surgeons. Since 2006 virtual simulation has been performed in selected patient cases affected by complex craniomaxillofacial disorders (n = 8) in addition to standard surgical planning based on patient specific 3d-models. Although for training, standard models are enough for young surgeons to practice, we still need to build an accurate and personalized model to simulate a surgery better.
Patients' CT images are considered appropriate references for this procedure. CT images are taken along the axis of the body, and each of them represents the structure of a plane that is perpendicular to the body axis. Information like the gray scale levels of each pixel, which can be used in building a volume model, are also contained. During an operation, the model should be able to give some haptic feedback as well as to update the changes on the models in real time.
In this project, we realize these functions with CHAI3D library. Omega 6 is the device we use for applying forces and receiving feedbacks.
