Dynamic AR Imaging for Anatomical Sites
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality imaging systems for anatomical sites are costly, limited in surgical applications, require calibration, and cannot accurately superimpose 3D images on moving anatomical sites, making them inefficient and dependent on skilled healthcare professionals.
Innovation Solution
A system comprising an image capturing device, display device, and a controller that automatically or manually identifies common reference elements to superimpose 3D images from CBCT or MRI on real-time images, allowing for dynamic augmented reality imaging independent of device position, using a smartphone or tablet with AI algorithms and AR frameworks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If distinct capture and display devices are used for augmented reality imaging, then imaging functionality is achieved, but manufacturing costs increase
Solution Approach 1:
The patent combines the image capturing device and display device into a single integrated device, eliminating the need for separate components and reducing manufacturing costs while maintaining augmented reality imaging functionality
Solution Approach 2:
The integrated device performs multiple functions including image capture, image display, and augmented reality processing within a single unit, reducing the overall system complexity and manufacturing requirements
2Measurement precision
If calibration devices and reference markers are used for positioning, then positioning accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The system uses the anatomical site itself as the reference for positioning and alignment, eliminating the need for external calibration devices or reference markers by leveraging natural anatomical features for image registration
3Measurement precision
If the anatomical site must remain stable and motionless for imaging, then image superimposition accuracy is maintained, but operational versatility is reduced
Solution Approach 1:
The system is designed to dynamically track and adapt to movements of the anatomical site in real-time, allowing the augmented reality images to remain accurately superimposed even when the patient moves, thereby enabling procedures without requiring the anatomical site to remain motionless
4Reliability
If multiple dedicated applications and high-technology devices are used, then imaging quality is improved, but ease of operation and accessibility are reduced
Solution Approach 1:
The system performs multiple complex functions including image capture, processing, display, and augmented reality generation within a single integrated device that operates automatically, eliminating the need for multiple dedicated applications and reducing operational complexity

AI summary
A system for dynamic augmented reality imaging of an anatomical site includes at least one image capturing device for capturing first real-time images of the site, at least one display device for displaying first images captured by the device, storage means for storing at least one second anatomical image of the site and an electronic device having a controller configured to receive and process the images. The controller is configured to display an augmented reality image obtained by superimposing images on the first image by identifying common reference elements of the images, and the common reference elements are identified automatically or manually. The second image is in 3D made up of portions of fan or cone beam computed tomography or magnetic resonance images depicting internal structures of the site. The augmented reality image is clipped to the site by the elements, irrespective of the spatial position of the electronic device.
