AI for ultrasound imaging

What software does with raw echoes

Ultrasound produces noisy, operator-dependent images. Machine learning has changed that in cardiology and obstetrics, and FDA has cleared the tools. S-WAVE™ is designed to bring the same capabilities to a fixed dental tray.

The S-WAVE™ pipeline

From raw echoes to a flagged change

Raw bench output before AI
Input: raw bench output, no AI

1 · Reconstruct

Echoes from every sensor position become a point cloud, a mesh and a surface.

2 · Clean and segment

Denoise, remove couplant and saliva artefacts, separate teeth from gum and bone, label each tooth.

3 · Register and measure

Align each scan to last month’s; measure enamel, gum thickness and bone level per tooth.

4 · Flag, don’t diagnose

Only changes above a threshold go to a dentist. The dentist decides; the software never does.

Capabilities

What AI already does for ultrasound, and what it will do here

Image quality guidance

Real-time feedback that tells the user the probe or tray is seated correctly. FDA authorized the first AI guidance for cardiac ultrasound by novices in 2020 (De Novo); the same idea is designed into the S-WAVE™ app.

Automatic measurement

Cleared echo tools measure ejection fraction without a sonographer; S-WAVE™ is designed to measure bone level and gum thickness per tooth automatically.

Change detection over time

Registration of serial scans is routine in radiology AI; applied monthly, it turns a scan into a trend.

Quality assurance

Reject unusable scans before they reach a dentist, so review time goes to real findings.

Training data

The acquired research data set and bench scans are the starting point; patient data will come only under the FDA testing plan with consent.

Updates under control

A Predetermined Change Control Plan lets an AI device improve after authorization within pre-agreed bounds, without a new submission each time.

Dental precedents

AI in dentistry FDA has already cleared

Radiograph analysis

Several AI products that detect caries and bone loss on dental X-rays have 510(k) clearance as aids to dentists. They prove the regulatory path for dental image AI, on radiographs.

Phone-photo monitoring

A De Novo authorization in 2023 for AI analysis of patient-taken dental photos established the home-monitoring category with clinician review.

What is new in S-WAVE™

The same two precedents, applied to ultrasound volumes instead of photos or radiographs, captured at home from a fixed tray.

Precedent devices are not KronosMD products and their clearances do not predict S-WAVE™’s. S-WAVE™ software does not exist yet; its standalone performance and clinical accuracy are part of the FDA testing plan.
