Point-and-Capture Wound Imaging for Diabetic Foot Ulcers

Consistent measurement is the foundation of every DFU treatment decision — but paper rulers, tracings, and add-on cameras create variability the trajectory curve cannot absorb. Point-and-capture imaging removes that noise.

The problem with traditional DFU measurement

• Ruler length × width overestimates area by 40% or more on irregular wounds
• Angle, lighting, and photographer change visit-to-visit reproducibility
• External imaging devices add cost, sterilization steps, and a second workflow
• Measurements sit in one system while notes and photos live in others

What point-and-capture does differently

1. No extra hardware. The clinician uses the phone or tablet already in hand at bedside.
2. Automatic segmentation. The AI outlines the wound perimeter, calculating length, width, area, and — where depth is inferable — volume.
3. Consistent scale. Reference calibration removes the angle and distance error that plagues freehand photos.
4. Native to the chart. The image, measurement, and timestamp land in the same record as the SOAP note and codes.

Why this matters for the diabetic foot

DFUs are often on curved plantar surfaces, near bony prominences, or tunneled under callus — exactly the geometries that defeat a ruler. Reproducible imaging is what lets the healing dashboard reliably flag a stalled wound at week four instead of week eight.

Fits the way DFU care actually happens

Much of DFU care now happens in patient homes, SNFs, and mobile clinics. AI-powered wound imaging and WoundScribe On Wheels were built for that reality — capture the wound where the patient is, get the measurement, chart, and code in one pass, and keep the trajectory intact across every site of service.
