FDA clears wave of fetal ultrasound AI, from biometry to anomaly

What Changed and Why It Matters

The FDA has cleared multiple AI tools for prenatal ultrasound. This spans routine measurements, anomaly detection, and targeted fetal heart analysis. Hospitals are now moving from pilots to clinical use.

Why this matters: obstetric ultrasound is high volume and skill-dependent. AI that standardizes measurements, flags anomalies, and guides views can raise detection rates and shorten scans. The signal is clear: regulators now see well-scoped, clinically-validated OB AI as safe and useful.

Here’s the part most people miss. This isn’t one breakthrough. It’s a stack forming across the workflow—biometry (Clarius), anomaly detection (Sonio), fetal heart (BrightHeart), and documentation/quality (BioticsAI). Adoption is following.

The Actual Move

  • Clarius gained FDA clearance in June 2024 for handheld OB AI.

“The OB AI model automatically performs fetal biometry measurements to estimate fetal age, weight and growth intervals.”

The model highlights key anatomy and places calipers. It runs on Clarius handheld scanners, bringing automation to point-of-care settings.

  • Sonio’s Suspect AI secured FDA clearance in February 2025 for anomaly detection.

“The AI tool enables earlier identification of subtle congenital malformations as early as 11 weeks.”

Multicenter research shows a 22% improvement in detection of fetal anomalies with Sonio’s AI-assisted ultrasound.

“Recent multicenter research showed a 22 percent improvement in the detection of fetal anomalies.”

  • BrightHeart earned FDA clearance for real-time fetal heart ultrasound analysis. Business Wire described it as a first in fetal heart ultrasound evaluations. Subsequent coverage emphasized improved screening for congenital heart defects (CHD) during routine scans.

“BrightHeart’s FDA-cleared AI platform enhances fetal heart screenings, improving detection of congenital heart defects during ultrasounds.”

  • Mount Sinai became the first in New York City to adopt an FDA-cleared AI tool to enhance fetal CHD screenings. This marks clinical uptake at a leading academic center.

“Mount Sinai Obstetricians First in New York City to Use FDA-Cleared AI Tool That Enhances Fetal Screenings for Congenital Heart Defects.”

  • BioticsAI announced FDA clearance for its fetal ultrasound AI platform, classified as software as a medical device. It targets prenatal workflow, quality, and anomaly support.

“FDA clearance means BioticsAI’s product is software as a medical device.”

Together, these moves validate AI across the prenatal ultrasound journey: measurement, guidance, screening, and documentation.

The Why Behind the Move

Zoom out and the pattern becomes obvious. OB ultrasound has clear tasks, high volume, and measurable endpoints.

  • Model
  • Narrow, supervised models excel on standardized views and measurements.
  • Real-time guidance (views, calipers, quality) is now reliable enough for clinics.
  • Traction
  • Early deployments focus on sonographer efficiency and detection rates.
  • Academic adoption (e.g., Mount Sinai) signals clinical trust.
  • Valuation / Funding
  • Regulatory milestones unlock hospital buying cycles and payer interest.
  • Clearance de-risks revenue forecasts and partnerships.
  • Distribution
  • Embedding into devices (Clarius) and reporting workflows (Sonio) beats standalone apps.
  • Handhelds expand reach to community and low-resource settings.
  • Partnerships & Ecosystem Fit
  • Hospitals need tools that fit existing ultrasound machines and reporting.
  • OEM and EHR/reporting integrations become the moat.
  • Timing
  • Post-2023, FDA pathways for SaMD are clearer for targeted use-cases.
  • Clinical evidence matured: multi-center studies, measurable endpoints.
  • Competitive Dynamics
  • Clear beachheads by modality: biometry (Clarius), anomaly detection (Sonio), fetal heart (BrightHeart), workflow/QC (BioticsAI).
  • Expect convergence via partnerships rather than one vendor doing everything.
  • Strategic Risks
  • Liability and over-reliance on AI suggestions.
  • Data drift across diverse machines and operators.
  • Reimbursement clarity for AI-assisted exams.

Bottom line: these companies are optimizing for workflow fit and trust over flashy models. The moat isn’t the model—it’s distribution, clinical evidence, and regulatory repeatability.

What Builders Should Notice

  • Pick a narrow, high-value task. Win it with evidence and workflow fit.
  • Distribution beats novelty. Integrate with devices and reporting, not just PACS.
  • Real-time guidance is the unlock. Feedback during capture > post-hoc analysis.
  • Prove outcomes that matter: detection rate, time saved, exam completeness.
  • Regulatory is a product strategy. Design for a repeatable 510(k)/De Novo path.

“Trust compounds. In regulated AI, it compounds into distribution.”
