| Outline of Final Research Achievements |
Neuronavigation has been widely used in neurosurgery, which localizes the 3D position of the affected area and displays the position on the preoperative medical image such as CT or MRI images. However, the displayed position becomes unreliable when brain is deformed by the loss of cerebral spinal fluid (CSF) or removable of the affected area. Such deformation is referred to as brain shift. In this work, a supporting system for neurosurgery was developed, which visualizes the estimated brain shift and stress distribution in the brain based on the real-time dynamics simulation. Furthermore, a semi-automated method to generate the finite element model of the brain of the patient from the preoperative medical images was developed.
