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.

Dragonfly provides radiation-free and non-invasive MRI scans, producing high-resolution images of the brain, spine, organs, blood vessels, and soft tissues in a single session. Depending on the selected service, imaging can include brain volume metrics, joint assessments, and vascular evaluation to detect structural abnormalities, lesions, or early-stage disease. Examinations are designed to identify a wide range of medical conditions before symptoms appear, including cancer, aneurysms, vascular blockages, degenerative spine disorders, and neurological changes. All scans are reviewed by board-certified radiologists who provide detailed reports for both patients and their healthcare providers. Dragonfly’s system allows for baseline imaging and ongoing monitoring, enabling comparison over time to track disease progression or confirm stability. This supports data-driven decision making for preventive care, treatment planning, and long-term health management.
