"Biomechanical models that simulate brain deformation are gaining attention as alternatives for brain shift compensation. One approach, known as the ''forced-displacement method'', constrains the model to exactly match the measured data through boundary condition (BC) assignment," scientists in the United States report.
"Although it improves model estimates and is computationally attractive, the method generates fictitious forces and may be ill-advised due to measurement uncertainty. Previously, we have shown that by assimilating intraoperatively acquired brain displacements in an inversion scheme, the Representer algorithm (REP) is able to maintain stress-free ...
