# STRAUS — Synthetic Cardiac Strain Ultrasound Dataset
|
| 16 |
+
|
| 17 |
+
## Description
|
| 18 |
+
|
| 19 |
+
The STRAUS dataset provides **18 synthetic patients** across **6 cardiac
|
| 20 |
+
conditions** (3 patients each):
|
| 21 |
+
|
| 22 |
+
| Condition | Patients |
|
| 23 |
+
|-----------|----------|
|
| 24 |
+
| Healthy | patient01–03 |
|
| 25 |
+
| LBBB | patient04–06 |
|
| 26 |
+
| LCx | patient07–09 |
|
| 27 |
+
| LAD | patient10–12 |
|
| 28 |
+
| RCA | patient13–15 |
|
| 29 |
+
| RCA2 | patient16–18 |
|
| 30 |
+
|
| 31 |
+
Each patient folder contains multi-modal imaging data:
|
| 32 |
+
|
| 33 |
+
- **cine/** — cine MRI images and meshes
|
| 34 |
+
- **tag1/, tag2/, tag3/** — tagged MRI images and meshes
|
| 35 |
+
- **us/** — ultrasound images and meshes
|
| 36 |
+
|
| 37 |
+
Additionally, **reference meshes** and a resource archive are included.

+
|
| 85 |
+
# Read an ultrasound frame
|
| 86 |
+
img = sitk.ReadImage("patient01_healthy/us/image/usfrm00.mhd")
|
| 87 |
+
volume = sitk.GetArrayFromImage(img)
|
| 88 |
+
print(f"Shape: {volume.shape}, dtype: {volume.dtype}")
