CETUS — Cardiac Echo Training and Ultrasound Segmentation
Description
The CETUS dataset contains 45 patients of real 3D echocardiography volumes acquired at two cardiac phases:
- End-Diastole (ED) —
patientXX_ED.nii.gz - End-Systole (ES) —
patientXX_ES.nii.gz
Ground-truth left-ventricular segmentation masks are provided as
patientXX_ED_gt.nii.gz and patientXX_ES_gt.nii.gz.

Format
- Volume format: NIfTI (
.nii.gz) - Typical shape: varies per patient (see metadata in NIfTI headers)
Usage
import SimpleITK as sitk
img = sitk.ReadImage("dataset/patient01/patient01_ED.nii.gz")
volume = sitk.GetArrayFromImage(img) # shape: (Z, Y, X)
print(f"Shape: {volume.shape}, dtype: {volume.dtype}")
