Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current patient-specific total joint replacement systems rely heavily on MRI scans, which are costly and not readily available in all markets, leading to accessibility issues and delayed or inhibited treatment processes due to the need for extensive user intervention and data processing.
Innovation Solution
A method to create 3D bone guides using bi-planar 2D images, such as X-ray data, allowing for the generation of 3D models that can be used for joint replacement procedures without the need for MRI scans, facilitating a guide system that is not sensitive to MRI reimbursement and availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If MRI scans are used to create patient-specific joint replacement guides, then the accuracy and detail of cartilage surface matching is improved, but the cost and accessibility of the treatment is worsened
Solution Approach 1:
The patent replaces expensive, reusable MRI imaging systems with disposable, low-cost 2D X-ray images that can be used once to create patient-specific guides, eliminating the need for costly MRI equipment while maintaining guide accuracy
Solution Approach 2:
The patent creates accurate 3D bone models and cartilage surface representations from 2D X-ray images through computational algorithms, producing virtual copies of anatomical structures that match the precision previously achievable only with MRI scanning
2Manufacturing precision
If MRI data is processed to create patient-specific guides, then the anatomical detail and guide precision is improved, but the time required for user intervention and data processing is worsened
Solution Approach 1:
The patent performs preliminary computational processing of 2D X-ray images to automatically generate 3D bone models and identify cartilage surfaces before guide manufacturing, eliminating the need for time-consuming manual user intervention during the actual guide creation process
Solution Approach 2:
The patent implements automated algorithms that independently process 2D images, automatically segment bone and cartilage structures, and generate patient-specific guides without requiring extensive user intervention, allowing the system to serve itself in the data processing workflow
3Reliability
If MRI equipment is used for joint replacement planning, then the quality of anatomical imaging is improved, but the cost of treatment and insurance reimbursement is worsened
Solution Approach 1:
The patent substitutes expensive, complex MRI equipment with inexpensive, widely available 2D X-ray imaging and computational processing, dramatically reducing treatment costs while maintaining the reliability needed for accurate joint replacement planning
Solution Approach 2:
The patent replaces the physical MRI imaging mechanism with a computational system that processes 2D X-ray images through algorithms to generate 3D anatomical models, substituting complex medical imaging hardware with software-based image processing

AI summary
Method, system, and program products are disclosed herein for creating a 3D model based on a plurality of received 2D medical images. Once the 2D images are received, a determination is made regarding any potential processing steps required to put the images into a standard view. Once the images are processed, a plurality of points are identified that are associated with a portion of an anatomical landmark. Various historical 2D images are then identified based on a comparison between the plurality of points. Using the historical information, a 3D image is generated of an anatomical feature of a patient.
