# STRAUS — Synthetic Cardiac Strain Ultrasound Dataset

## Description

The STRAUS dataset provides **18 synthetic patients** across **6 cardiac
conditions** (3 patients each):

| Condition | Patients |
|-----------|----------|
| Healthy   | patient01–03 |
| LBBB      | patient04–06 |
| LCx       | patient07–09 |
| LAD       | patient10–12 |
| RCA       | patient13–15 |
| RCA2      | patient16–18 |

Each patient folder contains multi-modal imaging data:

- **cine/** — cine MRI images and meshes
- **tag1/, tag2/, tag3/** — tagged MRI images and meshes
- **us/** — ultrasound images and meshes

Additionally, **reference meshes** and a resource archive are included.

```

## Format

- **Image format**: MetaImage (`.mhd` + `.raw` pairs)
- **Mesh format**: VTK (`.vtk`)
- **Archive**: `Resources (1).zip` contains additional resources

## Source

Original dataset page: <https://humanheart-project.creatis.insa-lyon.fr/multimodalityStraus.html>

## Usage

```python
import SimpleITK as sitk

# Read an ultrasound frame
img = sitk.ReadImage("patient01_healthy/us/image/usfrm00.mhd")
volume = sitk.GetArrayFromImage(img)
print(f"Shape: {volume.shape}, dtype: {volume.dtype}")
```
