Structure-based finite strain modelling of the human left ventricle in diastole [PDF]
, 2013 Finite strain analyses of the left ventricle provide important information on heart function and have the potential to provide insights into the biomechanics of myocardial contractility in health and disease. Systolic dysfunction is the most common cause

The right ventricle in congenital heart disease [PDF]
Heart, 2006 In patients with congenital heart disease the right ventricle (RV) may support the pulmonary (subpulmonary RV) or the systemic circulation (systemic RV). During the last 50 years evidence is accumulating that RV dysfunction develops in many of these patients and leads to considerable morbidity and mortality.

An algorithm for partitioning of right heart ventricle medial axis
Mathematical Modelling and Analysis, 2010 A right heart ventricle has a complex and irregular shape, this obscures analysis of ventricle surface movements. We are trying to quantitative evaluate morphological changes of right ventricle surface, these changes appear during heart beat cycle ...

Simulation of left ventricular function during dyskinetic or akinetic aneurysm
Biomolecules & Biomedicine, 2012 The purpose of our study was to simulate the hemodynamics of left ventricular function after left ventricular aneurysm (LVA) of various sizes and to validate the results of this computer based simulation with patient data.

Left-ventricle myocardium segmentation using a coupled level-set with a priori knowledge [PDF]
, 2006 This paper presents a coupled level-set segmentation of the myocardium of the left ventricle of the heart using a priori information. From a fast marching initialisation, two fronts representing the endocardium and epicardium boundaries of the left ...

Automatic segmentation of the left ventricle cavity and myocardium in MRI data [PDF]
, 2006 A novel approach for the automatic segmentation has been developed to extract the epi-cardium and endo-cardium boundaries of the left ventricle (lv) of the heart. The developed segmentation scheme takes multi-slice and multi-phase magnetic resonance (MR)
