AI interventional group: Participants in the intervention arm perform fetal biometry with the assistance of real-time Artificial Intelligence (AI) feedback software.
Study summary
Objective: To evaluate the impact of real-time AI feedback on fetal biometry accuracy and investigate the Expertise Reversal Effect-whether AI benefits diminish as user experience increases.
Design: A stratified randomized trial of 75 participants (25 Novices, 25 Intermediates, 25 Experts). Users are randomized 1:1 to either AI-assisted or manual measurement groups.
Outcomes:
* Primary: EFW accuracy (MAPE) compared to actual birthweight.
* Secondary: Procedure time, image quality, error relative to baseline scans, and cognitive workload (NASA-TLX).

Primary outcome measure(s)
To evaluate the sensitivity to change in ultrasound measurement accuracy when using AI-feedback compared to standard scanning — The two scans will be performed within a timeframe of 14 days. Mean absolute percentage error (MAPE), defined as the absolute difference between estimated fetal weight (EFW) and actual birth weight (ABW) divided by actual birth weight and expressed as a percentage, for AI-assisted and manual fetal biometry.
