Semi-automated cardiac segmentation on cine magnetic  resonance images using GVF-Snake deformable models
No opinion
The segmentation of left ventricular structures is necessary for the evaluation of the ejection fraction (EF) and the myocardial mass (LVM). A semi-automated 2D algorithm using connected filters and a deformable model allowing an accurate endocardial [...]

Image registration using the Morphon algorithm: an ITK implementation
starstarstarstarstar
Medical image registration is becoming a more and more useful component of a large number of applications. The presented method aims to enrich the ITK library. This method, called Morphon registration algorithm, computes a dense deformation field accepting [...]

Inverting deformation fields using a fixed point iteration scheme
starstarstarstarstar
Being able to quickly compute the inverse of a deformation field is often useful in the context of medical image analysis. While ITK supports this functionality, the current algorithms are slow and do not always yield accurate results. In this paper we [...]

Laplacian Mesh Deformation
starstarstarstarstar
Deforming a 3D surface mesh while preserving its local detail is useful for editing anatomical atlases or for mesh based segmentation. This contribution introduces new classes for performing hard and soft constraints deformation in a flexible design which [...]

Coupling Finite Element and Mesh-free Methods for Modelling Brain Deformation in Response to Tumour Growth
starstarstarstarstar
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. [...]

Statismo - A framework for PCA based statistical models
No opinion
This paper describes the Statismo framework, which is a framework for PCA based statistical models.Statistical models are used to describe the variability of an object within a population, learned from a set of training samples. Originally developed to model [...]

An ITK Implementation of the Symmetric Log-Domain Diffeomorphic Demons Algorithm
starstarstarstarstar
This article provides an implementation of the symmetric log-domain diffeomorphic image registration algorithm, or symmetric demons algorithm for short. It generalizes Thirion's demons and the diffeomorphic demons algorithm. The main practical advantages of [...]

Integration of Geometrical Boundary Conditions on Soft Tissue Characterization under large deformation
starstarstarstarstar
Soft tissue characterization with finite element (FE) modeling is important to develop a realistic model for medical simulation, since it is possible to display complex tool-tissue interactions during medical interventions. However, it is difficult to [...]
