Deep Biomechanically-Guided Interpolation for Keypoint-Based Brain Shift Registration
Tiago Assis, Ines P. Machado, Benjamin Zwick +2
Accurate compensation of brain shift is critical for maintaining the reliability of neuronavigation during neurosurgery. While keypoint-based registration methods offer robustness…
Automated modeling of brain bioelectric activity within the 3D Slicer environment
Saima Safdar, Benjamin Zwick, George Bourantas +5
Electrocorticography (ECoG) or intracranial electroencephalography (iEEG) monitors electric potential directly on the surface of the brain and can be used to inform treatment plann…
Recovery by discretization corrected particle strength exchange (DC PSE) operators
Benjamin F. Zwick, George C. Bourantas, Farah Alkhatib +2
A new recovery technique based on discretization corrected particle strength exchange (DC PSE) operators is developed in this paper. DC PSE is a collocation method that can be used…
Patient-specific solution of the electrocorticography forward problem in deforming brain
Benjamin F. Zwick, George C. Bourantas, Saima Safdar +5
Invasive intracranial electroencephalography (iEEG) or electrocorticography (ECoG) measures electric potential directly on the surface of the brain and can be used to inform treatm…
Immersed boundary finite element method for blood flow simulation
G. C. Bourantas, D. L. Lampropoulos, B. F. Zwick +3
We present an efficient and accurate immersed boundary (IB) finite element (FE) solver for numerically solving incompressible Navier--Stokes equations. Particular emphasis is given…
Simple and robust element-free Galerkin method with interpolating shape functions for finite deformation elasticity
George Bourantas, Benjamin F. Zwick, Grand Joldes +2
In this paper, we present a meshless method belonging to the family of element-free Galerkin (EFG) methods. The distinguishing feature of the presented meshless method is that it a…
Mathematical Modeling and Computer Simulation of Needle Insertion into Soft Tissue
Adam Wittek, George Bourantas, Benjamin F. Zwick +3
In this study we present a kinematic approach to modeling needle insertion into soft tissues. The kinematic approach allows the presentation of the problem as Dirichlet-type (i.e.…
Suite of Meshless Algorithms for Accurate Computation of Soft Tissue Deformation for Surgical Simulation
Grand Joldes, George Bourantas, Benjamin Zwick +7
The ability to predict patient-specific soft tissue deformations is key for computer-integrated surgery systems and the core enabling technology for a new era of personalized medic…
