fidoptSTRAUS 3D synthetic echocardiography
B-mode frames 0 and 10 of one simulated 3D echocardiographic sequence, one cardiac activation scenario, with the simulation's myocardial mesh vertices paired between the two frames (STRAUS).

- Images. The released Cartesian B-mode MetaImage data, not the RF polar data, with their spacing, origin, direction and int16 values. The source's MATLAB code main_map_gt2polar.m treats mesh coordinates as Cartesian millimetres on the B-mode grid, so no polar conversion is applied.
- Coordinates. The source's MATLAB view spans each axis from zero to Dimension×Spacing, while a MetaImage header puts the last voxel centre at (Dimension−1)×Spacing. The published header is used throughout; no sub-voxel precision beyond that convention is claimed.
- Truth. The simulated mesh motion, not annotated human heart motion. Frame 10 is a fixed index, not a claim that every scenario reaches end systole there.
- Ranked apart. Eight correlated simulated scenarios, a synthetic truth and nonstandard citation-ware terms.
- Licence. Preparing the data locally gives no permission to republish it.
No method has a result on every pair of this dataset yet.
Pair by pair
Click a score to look at that result: the fixed image, and over it the moving image after registration, with the annotations. Underlined scores have their image; for the others you see the pair without the result. A green cell gained against no registration on that pair, a red one lost.
About the data
- Test pairs
- All eight released scenarios are test cases, and no development case is made from other frames of the same simulations. The scenarios share one simulation framework and may share geometry: they are not eight independent patients.
- Truth
- landmarks a known deformation The same indexed vertices of the provider electromechanical myocardial meshes at frames 0 and 10. Topology and vertex count must agree. Vertices outside either image header grid or without a nonzero B-mode value in a 3×3×3 neighborhood in either frame are excluded before scoring; every surviving node is retained.
