ブレインシフト推定のための粒子法と有限要素法による連成解析

抄録

Neuronavigation has been widely used in brain surgery. However, it is known that the effects of brain shift make the navigation inaccurate. Brain shift is the deformation of a patient’s brain caused by removing the cerebrospinal fluid. Intraoperative MRI is one of the techniques to measure the brain shift. However, intraoperative MRI requires large and expensive equipments. Therefore, the method for estimating the brain shift with simple equipment will be useful. We aim to develop a dynamics simulator. In this study, we conducted a dynamics simulation to estimate the brain shift using the particle method and finite element method. In this paper, we describe a framework of MPS-FEM coupled analysis and the results of dynamics simulations.
