Key Points
- AI can make high‑quality ultrasounds available in remote areas.
- Handheld ultrasound combined with AI improves accuracy and reduces cost.
- Expanded access can lower maternal mortality worldwide.
Google researchers are testing a new way to fill the gap in ultrasound access. About two‑thirds of women worldwide cannot get an ultrasound when they are pregnant. Without this scan they miss vital information such as the baby’s growth, position, and due date. This gap leads to higher risks for both mother and child. Google researchers are testing a new way to fill the gap.
In a study with Northwestern University and Jacarand Health, the team created a special scanning method called a blind sweep. Operators move a small probe over the belly in a set pattern without prior training. The video captured by the device is then analyzed by an AI model that tells the operator whether to continue and estimates the baby’s age and position. The system runs entirely on the device, so it does not need power or internet.
The test showed that the AI‑driven ultrasound reached the same accuracy as a skilled sonographer. In fact, the model could predict gestational age and fetal presentation just as well as a trained sonographer. This means that even people who have never handled an ultrasound can produce useful images quickly.
The main benefit is that the technology brings expert‑level care to remote clinics and to frontline workers who otherwise would wait months for a specialist. By putting the tools directly in the hands of community health staff, the risk of missed complications drops. Improved maternal health outcomes could become a reality in places that previously lacked any ultrasound service.
If this proof of concept continues to grow, the next future for maternal health could involve AI‑enhanced scans on cheap handheld devices powered by Google’s cloud. The goal is to bring reliable prenatal information to every woman, regardless of location.
