Soft tissue deformation occurs during neurosurgery causing misalignment between preoperatively acquired images and the intraoperative brain. Compensation for this deformation is often accomplished using sparse intraoperative data from the exposed cortical surface combined with a biomechanical model. While simulations provide an important tool for testing these surface tracking algorithms, intraoperative conditions are most closely modeled using physical brain phantoms. We have developed a realistic silicone brain phantom and have used this phantom to test our surface tracking algorithm. The physical properties of this phantom allowed reliable testing of intraoperative surface tracking in a controlled environment
