Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote augmented reality communication systems for guided surgery lack robustness and accuracy due to communication lag, noise, and environmental factors such as radiation and temperature fluctuations, which can lead to errors and inaccuracies in image transmission and processing during medical procedures.
Innovation Solution
The implementation of an offsite device that uses timing and motion detection protocols, redundancy, error-detection and correction, and artificial intelligence to synchronize image analysis and modification, ensuring faithful image reconstruction and robust communication, even over long distances, by registering and transmitting illustrations and registration data between onsite and offsite surgeons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote augmented reality communication is used for guided surgery, then expert surgical guidance can be provided to remote locations, but communication lag and environmental factors cause errors and inaccuracies in image transmission
Solution Approach 1:
The system performs preliminary actions by pre-synchronizing timing protocols and motion detection parameters before actual surgical communication begins. Registration data and illustration frameworks are prepared in advance, allowing the system to quickly adapt to remote communication conditions while maintaining image transmission accuracy despite communication lag and environmental factors.
2Length of moving object
If image synchronization is performed over long distances, then remote surgical collaboration is enabled, but timing and motion detection errors increase due to communication lag
Solution Approach 1:
The system implements feedback mechanisms where timing and motion detection data are continuously monitored and adjusted based on actual communication conditions. Registration data from previous frames provides feedback to correct timing drift and motion detection errors in real-time, maintaining measurement precision even when communicating over long distances with inherent communication lag.
Solution Approach 2:
Timing protocols and motion detection parameters are pre-calibrated for the specific communication distance before surgery begins. This preliminary action establishes baseline synchronization values that account for the known communication lag, allowing the system to maintain timing and motion detection accuracy throughout the remote surgical procedure.
3Reliability
If robust error detection and correction is implemented, then communication reliability improves, but system complexity increases
Solution Approach 1:
The system introduces intermediary registration data and illustration frameworks that act as mediators between the complex error detection/correction mechanisms and the final image transmission. These intermediaries simplify the overall system complexity by providing structured data formats that are inherently more resistant to errors, reducing the burden on the error detection and correction subsystem while maintaining high communication reliability.
