Scanning Methodology: What, How, and Why

Scanning helps us capture the patient’s true shape quickly and accurately. Whether you use an iPhone, iPad with Structure, or other scanning tools, always pair your scans with accurate measurements to ensure the best outcome for your patient.

What Can Be Used for Scanning?

You have several options when it comes to capturing scans for fabrication:

Recommended Devices:

• iPhone X or newer – uses the built-in TrueDepth front-facing camera.
• iPad with a Structure Sensor (Structure Sensor website).

Recommended Apps:

• Galileo Scanner App (our preferred option) – Guide here.
• Third-party scanning apps such as Structure, Comb, or TechMed.

Other Options:

Some clinics and practitioners use professional scanning systems such as White Light Scanners or EinScan. Whichever option you are using, you can send us a supported file type, and we'll be able to use your desired scan!

What Can You Scan?

Our system can work with scans of:

• Residual limb
• Liner over limb
• Plaster positive
• Inside an existing socket - scanners cannot scan transparent objects. Add color by sprinkling baby powder or adding a spray.
• Inside a cast – How-to guide here.

How to Scan

Scanning with iPhone (TrueDepth Camera)

• Use an iPhone X or newer with the front-facing camera.
• Hold the device 19–34 cm (7–13 inches) away from the limb.
• Slowly move the device around the body part, ensuring complete coverage.
• If it’s difficult to use the front-facing camera directly, Galileo can provide a mirror attachment to make positioning easier.

Scanning with iPad + Structure Sensor

• Follow the workflow demonstrated in this video.
• Move steadily around the limb, keeping consistent distance.
• Ensure the scan captures the entire shape without gaps or overlapping distortions.

General Scanning Tips

• Always check lighting conditions (avoid glare or shadows).
• Make sure the patient remains still.
• Scan slightly beyond the area of interest to capture a complete shape.

Why Do We Scan?

Scanning provides the shape data we need to fabricate BK sockets and other devices. It allows us to create precise 3D models quickly and efficiently.

• Measurements still required: While scanning provides shape, it does not guarantee exact sizing. Always submit measurements alongside scans for reference.
• For AKs: If you prefer, you can order by numbers only (no scan required).
• Scan + Merge Option: For unique distal ends (e.g., fatty or irregular shapes), take a scan of the distal end and provide measurements. Our team will merge the data, preserving both shape and accurate sizing.
