3D Strain Assessment in Ultrasound (STRAUS): A Synthetic Comparison of Five Tracking Methodologies
Here is the supplementary material for my TMI 2013 paper. Unfortunately, the original link in the published PDF is broken. All data can be downloaded from the following links instead.

Generated Ultrasound Images
Ischemic Dataset Without Pericardium
Each contains the link to an image sequence and a mesh (segmentation of LV in the first frame) in VTK formats. The mesh is a volumetric tetrahedral mesh. There are 4 ischemic lesions and one normal case.

Ischemic Dataset With Pericardium
This dataset is based on the same set of mechanical simulations as the previous one, but images include the pericardium.

Dyssynchrony Dataset
This dataset includes one synchronous case in a dilated geometry and two versions of LBBB (partial is less pronounced).

SNR Datasets
This is a variant of the normal simulation (no pericardium). It corresponds to various contrasts between myocardium and blood pool. The reference sequence corresponds to alpha = 0.5. The links below point to the sequences for alpha = 0.75, 1, and 1.5.

Reference Volumetric Meshes
Link to volumetric meshes containing AHA regions and local directions (longitudinal, radial, circumferential).
https://straus.decraene.org/StacomSecondDataSet/results/refMeshes.zip
All meshes are stored in VTK unstructured grid format with arrays (aha, circs, rads, longs) for directions and segments. The AHA array is specified both on cells and points. The Normal mesh can be taken as the reference mesh for all ischemic (with and without pericardium). For the Dyssynchrony dataset, one reference mesh is provided for each simulation.
Strain
Link to radial, circumferential, and longitudinal strain computed on the ground truth using the set of directions provided in reference meshes.

The code for computing strain is provided here:

Matlab Scripts
Matlab code used for generating figures in the paper is also provided for convenience. It uses a conversion executable (ConvertVtkUg2Mat) for converting VTK volumetric meshes to Matlab. It needs to be recompiled separately using CMake and VTK.

Tracking Results
For each evaluated methodology, these links point to the deformed volumetric meshes. Tracking error is stored as an array (DispError) on points. Strains are stored as arrays on cells (strainl, strainr, strainc). For each methodology, results are grouped by dataset (ischemic without pericardium, ischemic with pericardium, and dyssynchrony). Results for the SNR experiments are given in a separate archive. The highest SNR level corresponds to the normal case in “ischemyNoPc”.
