## Abstract

The ability to capture an undistorted image of the foot or foot and ankle is essential to the production of effective custom orthotics and shoes. This patent solves the problem of providing an accurate three-dimensional measurement of an undistorted foot/ankle by using a system involving the automated and controlled orbit of a point cloud capture device around the foot/ankle with the foot/ankle in a non-weight bearing position so as to capture a three-dimensional image.

## Claims

### Claim 1

A system of capturing a three-dimensional measurement of an undistorted foot and ankle, the system comprising: a bench or chair on which a patient sits, wherein a point cloud capture device is rotated around the patient's foot in the shape of a semicircle from the lateral ankle to the plantar foot region to the medial ankle of the same foot, wherein the point cloud capture device is attached to a wheel, with a diameter between two and three feet, that is attached to and stabilized by a support frame, wherein the wheel is rotated by a stepper motor which rotates a rubber band that is wrapped around the wheel, wherein the stepper motor's motion is controlled by a computer.

### Claim 2 (depends on 1)

The system of claim 1 wherein the point cloud capture device is integrated into a mobile phone.
