Estimation of 3D left ventricular deformation from echocardiography
216
TL;DR: A methodology for estimating cardiac deformations from 3D echocardiography (3DE) that shows good agreement with previously published results in the literature and exhibits a high correlation with strains produced in the same animals using implanted sonomicrometers.

Estimating myocardial motion by 4D image warping
TL;DR: Experimental results on real data demonstrate good performance of the proposed method for cardiac image registration and motion estimation, and the motion estimation is validated via comparisons with motion estimates obtained from MR images with myocardial tagging.

TL;DR: A new approach is presented for the assessment of a 3-D anatomical and functional model of the heart including structural information from magnetic resonance imaging (MRI) and functional information from positron emission tomography (PET) and magnetocardiography (MCG).

TL;DR: In this article, a radiofrequency (RF) based speckle tracking technique was employed to image the entire two-dimensional (2D) transmural deformation field in full echocardiographic views and was validated against tagged magnetic resonance imaging (tMRI) in normal as well as reperfused (i.e., treated myocardial infarction [MI]) human left ventricles.

PDE-constrained optimization in medical image analysis
TL;DR: The ultimate goal of the work is the design of inversion methods that integrate complementary data, and rigorously follow mathematical and physical principles, in an attempt to support clinical decision making, which requires reliable, high-fidelity algorithms with a short time-to-solution.

Stochastic Relaxation, Gibbs Distributions, and the Bayesian Restoration of Images
Stuart Geman,Donald Geman +1 more
TL;DR: The analogy between images and statistical mechanics systems is made and the analogous operation under the posterior distribution yields the maximum a posteriori (MAP) estimate of the image given the degraded observations, creating a highly parallel ``relaxation'' algorithm for MAP estimation.

A practical guide to splines
Carl de Boor
- 01 Jan 1978
TL;DR: This book presents those parts of the theory which are especially useful in calculations and stresses the representation of splines as linear combinations of B-splines as well as specific approximation methods, interpolation, smoothing and least-squares approximation, the solution of an ordinary differential equation by collocation, curve fitting, and surface fitting.
A Practical Guide to Splines.
TL;DR: This book is based on the author's experience with calculations involving polynomial splines.
