CAMUS - 2-D Echocardiographic Ultrasound Dataset

This dataset is a zea-format (HDF5) conversion of the CAMUS dataset for multi-structure segmentation in 2-D echocardiography.

Property	Value
Modality	2-D transthoracic echocardiography
Patients	500
Views	2-chamber (2CH) and 4-chamber (4CH) apical
Splits	train (1-400), val (401-450), test (451-500)

Conversion

This dataset was downloaded, converted to zea format, and uploaded using the zea data converter:

zea convert camus <src> <dst> --download

Dataset structure

train/
  patient0001/
    patient0001_2CH_half_sequence.hdf5
    patient0001_4CH_half_sequence.hdf5
  ...
val/
  patient0401/ ...
test/
  patient0451/ ...

Each HDF5 file follows the zea data format and contains:

data/image/values — scan-converted B-mode sequence in dB, shape (n_frames, H, W), float32; x=0 at apex centre
data/image/coordinates — per-pixel Cartesian positions in metres, shape (H, W, 3) [x, y=0, z]
data/image_polar/values — polar-resampled B-mode sequence, shape (n_frames, n_r, n_theta), float32
data/image_polar/coordinates — Cartesian [x, 0, z] positions of polar pixels in metres, shape (n_r, n_theta, 3)
data/segmentation/values — multi-label bool segmentation, shape (n_frames, H, W, 4)
data/segmentation/labels — ["unannotated", "LV_endo", "LV_myo", "LA"]; unannotated frames have only the first channel set
data/segmentation/coordinates — same grid as image/coordinates
metadata/subject — patient ID, sex, age
metadata/credit — full citation string
metadata/text_report — ejection fraction, frame rate, image quality
metadata/annotations/view — "2CH" or "4CH" repeated for all frames
metadata/annotations/label — "ED" / "ES" for the corresponding frames, "" otherwise
metadata/annotations/image_quality — "Good" / "Medium" / "Poor"
