About

SagittalMeter Lite

This application assists medical practitioners in measuring crucial sagittal balance parameters directly from sagittal X-rays. It helps analyze spine problems and pre-operative planning by calculating pelvic incidence, pelvic tilt, and sacral slope.

Highlights
  • Measure sagittal balance parameters
  • Directly use phone on X-rays
  • Calculate Pelvic Incidence (PI)
  • Calculate Pelvic Tilt (PT)
  • Calculate Sacral Slope (SS)
  • Aid in spine problem analysis

SagittalMeter is an educative app to easily measure sagittal balance parameters, by directly placing your phone on the sagittal X-Rays. The sagittal balance is an imperative factor to take into consideration for all practitioners treating spine problems and particularly for surgeons during the pre-operative phase. The compensatory mechanisms of a sagittal unbalanced spine may prevent a successful surgery outcome. A fundamental understanding of a correct sagittal alignment is strongly recommended in determining the correct use of fusion or non fusion devices. SagittalMeter enables you to measure 3 fundamental angles which are essential to analyze sagittal alignment: • Pelvic incidence (PI) • Pelvic tilt (PT) • Sacral slope (SS)

About

BackSCNR

This radiation-free tool uses surface topography to screen and monitor scoliosis in adolescents. It captures 3D torso scans, analyzes asymmetries, and estimates curve angles to support clinical decision-making.

Highlights
  • Radiation-free scoliosis screening
  • 3D torso capture with TrueDepth or Structure Sensor
  • Asymmetry analysis and curve angle estimation
  • Supports clinical decision-making
  • Rapid analysis via secure web platform

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. For more details, visit https://backscnr.com Disclaimer: BackSCNR is intended to aid in the screening and management of postural conditions and is not a substitute for professional medical diagnosis or treatment planning. 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.
