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.

Usage

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}")
