Image-Guided Surgery

Frameless guidance systems are needed to help surgeons plan exact locations for incisions, define margins of tumors and precisely locate critical structures. We describe an automatic method for registering clinical data, such as segmented MRI or CT, with any view of the patient, with particular demonstration on neurosurgery examples. The method enables mixing live video of the patient with the segmented 3D MRI or CT model, supporting enhanced reality techniques for planning and guiding procedures, and for interactively, non-intrusively viewing internal structures. The method is currently being used by surgeons for direct guidance and planning in the operating room. Extensions of the method to be discussed include image guided biopsies, focused therapeutic procedures and clinical studies involving change detection over time sequences of images.
