EchoXFlow Demo
This repository contains a small demo export of EchoXFlow data with one examination only.
Full dataset: Ahus-AIM/EchoXFlow.
Contents
croissant.json: MLCommons Croissant metadata for the exported collection.exams/exam_2158f4615166f365/: the single included examination.exams/exam_2158f4615166f365/recording_*.zarr/: Zarr-backed recordings extracted from the examination.
The demo contains:
- 1 examination
- 79 extracted recording Zarr groups
Data Format
Each recording is stored as a directory-backed Zarr group. Recording-level metadata and array references are stored inside each Zarr root. The included Croissant metadata describes the public record layout and the relationship between exams, recordings, arrays, timestamps, and annotations.
The source export was generated by the EchoXFlow DICOM MPL extraction pipeline on May 6, 2026.
