In neurosurgery, effects of deformation should be considered to avoid damaging brain tissues. The goal of this study is to develop an automatic path planner considering the deformation of brain tissues. This paper shows a scheme which combines FEM (Finite Element Method) and an optimization method for optimization of retraction in order to approach a deep part of a brain. Also, evaluations of two...
Dissection and removal of lesion area are fundamental operations in brain surgery. In order to correctly reproduce dissection and removal in brain surgery haptic simulation, mechanical properties of brain tissue must be investigated. In this work, porcine brains are used as specimens. Mechanical properties such as density, Poisson's ratio, Young's modulus, damping coefficient, and fracture stress...
