Integrated Imaging System for Orthopedic Joint Motion Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthopedic diagnostic methods are limited in their ability to accurately detect and assess joint pathologies, particularly in the lumbosacral region, due to imprecision and inconclusiveness, leading to undiagnosed or misdiagnosed cases of back pain, and fail to account for muscle involvement and gravitational forces during weight-bearing postures.
Innovation Solution
An integrated imaging system with real-time tracking and feedback loops that adjusts the imaging environment to optimize diagnostic information, using a motion device and imaging device communication to control patient positioning and imaging quality, reducing variability and enhancing diagnostic accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current orthopedic diagnostic methods are used, then the diagnostic process is simple and quick, but the measurement precision and diagnostic accuracy are insufficient
Solution Approach 1:
The patent combines multiple diagnostic components into an integrated system: motion capture devices, force plates, electromyography sensors, and imaging systems are merged into a unified diagnostic platform. This integration allows simultaneous measurement of joint motion, gravitational forces, and muscle activity, thereby improving diagnostic accuracy while managing complexity through coordinated operation of components.
Solution Approach 2:
The patent introduces computer-based processing and control systems as intermediaries between the various sensors and the final diagnostic output. These intermediaries process raw data from motion capture, force plates, and EMG sensors, and generate meaningful diagnostic information, thereby bridging the gap between complex measurements and clinical interpretation.
2Reliability
If traditional diagnostic methods are used, then the ease of operation is high, but the reliability and consistency of diagnostic results are poor
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors joint motion and gravitational forces, and uses this information to adjust measurements and provide real-time diagnostic feedback. This feedback loop ensures consistent application of diagnostic criteria and improves reliability by allowing operators to verify and adjust measurements based on system-generated information.
Solution Approach 2:
The patent systematically varies and controls multiple parameters including joint angle, loading conditions, and muscle activation states during diagnostic procedures. By standardizing these parameter changes through computer control, the system ensures consistent measurement conditions across different patients and examinations, thereby improving diagnostic reliability.
3Difficulty of detecting and measuring
If comprehensive imaging and tracking systems are implemented, then the detection capability for joint motion abnormalities is improved, but the device complexity and cost increase
Solution Approach 1:
The patent divides the diagnostic system into separate functional modules: motion capture subsystem, force measurement subsystem, electromyography subsystem, and imaging subsystem. Each module can be independently optimized and calibrated, making the overall complex system more manageable while maintaining high detection capability through specialized measurement in each domain.
