Nonlinear Elastic Registration with Unbiased Regularization in Three Dimensions
We propose a new nonlinear image registration model which is based on nonlinear elastic regularization and unbiased registration. The nonlinear elastic and the unbiased regularization terms are simplified using the change of variables by introducing an [...]

Coupling Finite Element and Mesh-free Methods for Modelling Brain Deformation in Response to Tumour Growth
Very little is known about the deformation effects of tumour growth within the brain. Computer simulations have the potential to calculate such deformations. A method for computing localised high deformations within the brain's soft tissue is presented. [...]

Cardiac Motion Recovery by Coupling an Electromechanical Model and Cine-MRI Data: First Steps
We present a framework for cardiac motion recovery using the adjustment of an electromechanical model of the heart to cine Magnetic Resonance Images (MRI). This approach is based on a constrained minimisation of an energy coupling the model and the data. Our [...]

Multimodal Registration of White Matter Brain Data via Optimal Mass Transport
The elastic registration of medical scans from different acquisition sequences is becoming an important topic for many research labs that would like to continue the post-processing of medical scans acquired via the new generation of high-field-strength [...]

Fast image-based model of mitral valve closure for surgical planning
Surgical repair of the mitral valve results in better outcomes than valve replacement, yet diseased valves are often replaced due to the technical difficulty of the repair process. A surgical planning system based on patient-specific medical images that [...]

Orientation definition of anisotropy is important to finite element simulation of bone material properties
The assignment of bone material properties to finite element model is a fundamental step in finite element analysis and has great influence on analysis results. Most work done in this area has adopted isotropic assignment strategy as its simplicity. However, [...]

Cardiac motion estimation using multi-scale feature points
Heart illnesses influence the functioning of the cardiac muscle and are the major causes of death in the world. Optic flow methods are essential tools to assess and quantify the contraction of the cardiac walls, but are hampered by the aperture problem. [...]

Assessment of Peri-Articular Implant Fitting Based on Statistical Finite Element Modeling
We present a framework for statistical finite element analysis allowing performing statistical statements of biomechanical performance of peri-articular implants across a given population. In this paper, we focus on the design of orthopaedic implants that fit [...]

Predicting implant stability: in vitro validation in artificial bone
Primary stability of osseointegrated implants is necessary for short and long-term success of the treatment. This paper presents a method to help clinicians preoperatively assess this primary implant stability. The method combines a planning software with a [...]

Simulation of Active Cardiac Dynamics with Orthotropic Hyperelastic Material Model
Meaningful physical models are important for studying cardiac physiology, such as quantitative assessments of pathology via changes in model parameters, and recovering information from medical images. In order to achieve realistic deformation studies, an [...]
