Patient-specific Modeling of Cardiac Biomechanics in Repaired Tetralogy of Fallot

Experiences with the PTB prosthesis.

1 State Supervisor of Prosthetic Services, Ministry of Social Affairs, Helsinki, Finland. The original patellar-tendon-bearing (PTB) prosthesis was constructed at the Biomechanics Laboratory of the University of California. For details regarding the anatomical and physiological considerations (J), the biomechanics (4), and the construction (2), the reader is referred to the June 1962 issue of A...

Fully Eulerian finite element approximation of a fluid-structure interaction problem in cardiac cells

We propose in this paper an Eulerian finite element approximation of a coupled chemical fluid-structure interaction problem arising in the study of mesoscopic cardiac biomechanics. We simulate the active response of a myocardial cell (here considered as an anisotropic, hyperelastic, and incompressible material), the propagation of calcium concentrations inside it, and the presence of a surround...

Artificial intelligence in sports biomechanics: new dawn or false hope?

This article reviews developments in the use of Artificial Intelligence (AI) in sports biomechanics over the last decade. It outlines possible uses of Expert Systems as diagnostic tools for evaluating faults in sports movements ('techniques') and presents some example knowledge rules for such an expert system. It then compares the analysis of sports techniques, in which Expert Systems have foun...

Sampled-Data H-Filtering for Robust Kinematics Estimation: Applications to Biomechanics-Based Cardiac Image Analysis

A sampled-data H∞ filtering strategy is proposed for the estimation of cardiac kinematic functions from periodic medical image sequences. Given the biomechanics-based myocardial dynamics, stochastic multi-frame filtering frameworks are constructed to deal with the parameter uncertainty of the biomechanical constraining model and the noisy nature of the imaging data in a coordinated fashion. As ...
