We are pleased to share that our report on the outcomes of the ACOUSLIC-AI Challenge has been published in Medical Image Analysis under the title “ACOUSLIC-AI challenge report: Fetal abdominal circumference measurement on blind-sweep ultrasound data from low-income countries”.

Read the open-access article here: https://doi.org/10.1016/j.media.2025.103640.

In this report, we present the performance of the top 3 AI models, which were evaluated against expert-annotated blind-sweep scans and clinical ground truth collected during routine obstetric care.

Key Highlights:

  • First study to address fetal AC measurement using blind-sweep ultrasound data
  • Introduced first publicly available blind-sweep ultrasound dataset from in low-income settings
  • Feasibility of automated AC measurement from scans acquired by novice operators using low-cost probes
