MATERNA-ATLAS — Harmonized Multimodal Maternal-Fetal Health Atlas

This upload contains the full technical documentation and a free evaluation sample (266 real episodes with matching raw signals and imaging indices) — not the full dataset. The complete atlas — 12,860 linked episodes, 552 raw CTG and 326 raw EHG recordings, two fetal-ultrasound benchmarks, group-safe splits and reference baselines — is available at: https://sentineldata.com.ua/dataset/materna-atlas-maternal-fetal-health-atlas Sample contents: File Rows Content materna_atlas_sample_episodes.parquet 266 40 real episodes per source (all 26 for tpehgt) from 7 sources — Arm A 120 / Arm B 80 / Arm C 66 — same 26-column schema as the full episode table materna_atlas_sample_signals_ctu_uhb.parquet 80 Raw FHR + UC waveform for the 40 sampled ctu_uhb episodes (2 channels each) materna_atlas_sample_signals_tpehg.parquet 120 Raw 3-channel EHG waveform for the 40 sampled tpehg episodes materna_atlas_sample_signals_tpehgt.parquet 104 Raw waveform (EHG1–3 + TOCO) for all 26 tpehgt episodes materna_atlas_sample_hc18_index.parquet 60 60 of 1,334 HC18 image records (metadata only, no pixels) materna_atlas_sample_fetal_planes_index.parquet 90 15 images per class × 6 classes (metadata only, no pixels) MATERNA-ATLAS_Sample_Passport_EN.pdf — Sample passport (inside the archive) The sample is a real, unmodified random subset drawn directly from the delivered full-dataset files (seed 42) — not a ...
