Abstract: We will present our recent work on real-time 3D deformable registration for Image Guided Diagnosis and Therapy for brain cancer and Deep Brain Stimulation (DBS). Minimizing residual tumor and maximizing preservation of healthy brain tissue have been associated with the improved prognosis and lower morbidity for the brain tumor patients undergoing surgical management. These tasks are facilitated by image-guided surgery. However the challenge with using image guided system during these procedures is the significant brain shift during tumor resection. The overall goal of our work is to provide improved accuracy of tumor resection by accurately fusing in real-time pre-operative MRI with intra-operative MRI or CT to account for the brain shift. In the second part of the talk we will address the application of the same technology to DBS for Parkinson’s disease. Finally, if there is time and interest we will conclude with our efforts in anatomic modeling for brain AVM (arteriovenous malformation) and blood flow diversions for brain aneurysms with stents.
