This app uses the Structure SDK / TrueDepth camera for 3D scanning. Supported device list (updated regularly): https://techmed3d.zohodesk.com/portal/en/kb/articles/minimun-device-requirements Our Pro-Tech 3D Scan app is an advanced scanning technology in association with TechMed 3D, the leaders in CAD CAM Software. They have developed an enhanced method of measuring and scanning the body rather than casting your patients. You begin by providing your company and patient information which gives you the ability to track your patients, select appropriate orthometry form, and choose an extremity to scan. You simply calibrate the scanner software and then scan your patient either circumferential or bivalve for those challenging patients that must be scanned only supine. If you choose to scan your patient bivalve you simply use a convenient merging tool, which provides you with an accurate model of your patient. Download our free app, submit your scan, and we do the rest by using our state of the art modification tools. This will refine your model and manufacture your custom superior orthotic device, all while giving you time to see more patients. This app provides our practitioners with the highest standards for design, precise fit, and comfort. *This app is specifically designed to work with an Apple iPad® and both the Structure Sensor and the Structure Sensor (Mark II).
