AI-assisted “blind-scan” ultrasound technology supports maternal and child health care at the grassroots level: A multi-center, prospective study validates its cross-regional generalizability.
Google’s research team, in collaboration with clinical institutions, conducted a prospective multicenter study that demonstrated an AI‑driven “blind‑scan” ultrasound protocol—using low‑cost, portable probes operated by non‑ultrasound specialists—achieved gestational age assessment accuracy comparable to expert‑level ultrasonic biometry in both Chicago and Nairobi (mean absolute error of 4.18 days vs. 4.48 days), without requiring local data fine‑tuning. This offers a viable pathway to expand prenatal ultrasound coverage in resource‑limited settings.
