Smart Photo is an imaging option in the Parable app that uses data points from multiple 2D images to digitally capture topographic measurements of a wound/lesion.

Smart Photo uses your device's built-in camera and does not require any additional sensor hardware.

Smart Photos automatically measure length and width and generate a real Surface Area measurement--a critical metric for evaluating wound healing progression.

Smart Photos do not measure depth or volume, and do not produce a 3D topographical model of the view, unlike 3D Smart Scans or 3D Cloud Scans (Sensorless).

Note: 2D Smart Photo is only available on iOS on iPhone 6s or newer iPhone / iPad devices.

Performing Smart Photos

When you start an assessment in Parable, select the "Smart Photo 2.0" option as your imaging type.

Imaging type selection - Parable mobile app

The first time you perform a Smart Photo, you'll see an on-screen visualization of the scanning process, along with instructions. You can review these instructions again at any time by pressing the "?" icon at the top right of the screen.

First, position your device for a clear view directly over the center wound, then tap "Start Scan"
Gray arches will appear on-screen to guide your scan
Begin scanning by moving your device along any of the arches from the center out to the edges (and back)
1. Scan over and across the wound by following each arch like a 'track' or guideline
2. Tilt and align your device to match the curvature of the arches as you scan
Successfully scanning turns the arches from gray to yellow, indicating those angles have already been scanned
1. This process ensures the wound is scanned from a variety of angles, refining the resulting measurements
Once both arches are fully yellow, scanning is complete

Tracing

After saving your scan, you'll automatically proceed to tracing. Toggle between different tracing options at the bottom of the screen. In-app guidance is available for each tracing type by pressing the "?" icon at the top-right.

**Tip:** you can edit the trace via touch controls by nudging the wound boundary to expand or contract.

Please see the Smart Trace and Manual Trace article for more information about identifying wound/lesion site boundaries in Parable. After an acceptable outline has been traced, the 2D Smart Photo process is complete, and you can proceed with Supporting Photos and Clinical Documentation.
