Differential Geometry Revisited by Biquaternion Clifford Algebra
In the last century, differential geometry has been expressed within various calculi: vectors, tensors, spinors, exterior differential forms and recently Clifford algebras. Clifford algebras yield an excellent...

Estimation of In Vivo Myocardial Fibre Strain Using an Architectural Atlas of the Human Heart
We propose a methodology to estimate 3D+time maps of left ventricular (LV) fibre strain from human structural and dynamic MRI data. A biomechanical finite element model integrates fibre direction throughout th...

Statistical Analysis of the Human Cardiac Fiber Architecture from DT-MRI
A statistical atlas of the cardiac fiber architecture is built for the first time with a human dataset of 10 healthy ex vivo hearts acquired using DT-MRI. The atlas is constructed using an efficient semi-automate...

Driving Dynamic Cardiac Model Adaptation with MR-Tagging Displacement Information
The dynamic deformable elastic template (DET) model has been previously introduced for the retrieval of personalized anatomical and functional models of the heart from dynamic cardiac image sequences. Dynamic ...

Respiratory Motion Estimation from Cone-Beam Projections Using a Prior Model
Respiratory motion introduces uncertainties when planning and delivering radiotherapy for lung cancer patients. Cone-beam projections acquired in the treatment room could provide valuable information for build...

Locally Adapted Spatio-temporal Deformation Model for Dense Motion Estimation in Periodic Cardiac Image Sequences
We recently introduced a continuous state space parametric model of spatio-temporal transformations and an algorithm, based on Kalman filtering, to represent motion in an image sequence describing a periodic p...

A Hyperelastic Deformable Template for Cardiac Segmentation in MRI
This article proposes a hyperelastic 3D deformable template for the segmentation of soft structures. It relies on a template, which is a topological, geometrical and material model of the structure to segment....

A Realistic Anthropomorphic Numerical Model of the Beating Heart
A realistic anthropomorphic numerical model of the beating heart is presented. It includes the main cardiac anatomical structures, vessels junctions and part of the coronary network. Its main feature is that i...

Evaluation of Two Free Form Deformation Based Motion Estimators in Cardiac and Chest Imaging
In the context of motion estimation of the heart and thoracic structures from tomographic imaging, we investigated two free form deformations (FFD) based non linear registration methods as motion estimators. S...

A 3-D Model-Based Approach for the PET-Functional and MR-Anatomical Cardiac Imaging Data Fusion
In this paper, an approach for the assessment of 3-D functional maps of the heart is proposed. It relies on the model-based coregistration of MR anatomical and PET metabolic images and the extraction of an ind...
