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 SpinalTech3D Scan app refines the process of ordering custom spinal orthoses in the Orthotic field. You can order from Spinal Technology by electronically integrating 3D scans, images, practitioner instructions, and filling out our custom spinal and scoliosis orthometry forms.  With this app, practitioners can take 3D scans, include images to denote anatomical landmarks, then write comments and instructions on the images and, using Tech Med 3D software, combine all images and documentation into one electronic file that is emailed to Spinal Technology, Inc.  When the file is received in-house, we use our proprietary software to modify the image based on the patient information and the brace design that the practitioner selects. The modified file is loaded to one of our six carvers to produce a positive model of the patient’s torso that is further fine-tuned for precise fabrication of a custom orthosis.   

The SpinalTech3D Scan app is designed to work seamlessly with an iPad and Structure Scanner.  There is no cost for the SpinalTech3D Scan app, no conversion fees nor any added cost associated with this technology, yet it will improve accuracy and save time.

BackSCNR (Back Scanner) is a scoliosis screening and monitoring support tool designed to aid in the management of Adolescent Idiopathic Scoliosis (AIS). Using advanced Surface Topography (ST), the app provides a radiation-free and non-invasive way to assess the 3D shape of the human torso, offering a safe alternative for frequent monitoring without exposure to harmful X-rays. Developed through years of leading academic research, BackSCNR is registered with Health Canada as a Class I Software as a Medical Device (SaMD). It is intended for use in individuals aged 10–18 years to assist clinicians in quantifying torso asymmetries and estimating curve angles associated with AIS. Key Features: - Flexible 3D Torso Capture: Capture high-accuracy 3D scans using either the Structure Sensor accessory or your iPhone’s built-in TrueDepth camera. - Asymmetry Analysis: Aids in identifying and tracking torso asymmetries over time. - Clinical Support: Provides detailed metrics, including estimated Cobb angles and deviation color maps, to support clinical decision-making. - Rapid Results: Upload and process models to receive analysis within minutes on our secure web platform. How it Works: 1. Select Your Hardware: The app automatically detects if a Structure Sensor is connected and will default to it for scanning. If no sensor is detected, the app defaults to the iPhone’s TrueDepth camera. 2. Capture the Scan: Follow the in-app guidance to take a 3D scan of the patient's torso. 3. Analyze & Report: Upload the data to the secure BackSCNR website for automated analysis and reporting. Compatibility: - TrueDepth:** Compatible with TrueDepth-enabled iPhones (iPhone X and newer). - OS: Supported on modern iOS devices (iPhone X and later) and compatible iPads. - Sensors: Optimized for Structure Sensor 3; also supports Mark II and Pro models.

Always seek the advice of a physician or other qualified healthcare provider with any questions regarding a medical condition. Use of the device for diagnosis should only be done in consultation with a qualified healthcare professional.
