Google researchers used AI to interpret blind sweep ultrasounds. Healthcare workers with eight hours of training performed the scans. The model detected gestational age and fetal position as accurately as sonographers. It runs on-device without needing electricity or Wi-Fi. The study covered 2,000 mothers in Nairobi and Chicago. Traditional ultrasounds need two years of sonographer training. Portable devices are cheaper but still require expert operators. The approach aims to expand prenatal care access in under-resourced areas.
What changed
Prenatal ultrasounds required a trained sonographer and precise probe movements.
What it unlocks
Non-specialists can now perform ultrasounds and get accurate gestational age and fetal position readings.
