Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical image processing systems face delays and instability in video display due to recognition processing, which can hinder user operations and lead to overlooked lesions during medical procedures.
Innovation Solution
A medical image processing system with multiple processors that switch between primary and secondary video signals based on recognition processing status, ensuring stable video display without delays by prioritizing primary signals when recognition processing is stopped or abnormal, and seamlessly transitioning back when processing resumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If recognition processing is performed on medical images to detect regions of interest and classify lesions, then diagnostic accuracy and lesion detection capability are improved, but video display delay and system response time increase
Solution Approach 1:
The system divides video processing into two independent pathways: a fast pathway that processes video signals for real-time display without recognition processing, and a slow pathway that performs recognition processing for lesion detection. This segmentation allows the system to maintain real-time display performance while simultaneously providing accurate lesion detection capabilities.
Solution Approach 2:
The system performs recognition processing in advance on captured medical images to generate region-of-interest data and lesion classification results before they are needed for display. This preliminary action allows the processed information to be ready for immediate presentation, reducing perceived delay when results are displayed.
2Measurement precision
If recognition processing is performed to provide diagnosis support functions, then lesion detection capability is improved, but system stability and video display reliability deteriorate due to processing failures
Solution Approach 1:
The system prepares backup video signal pathways and error handling mechanisms in advance to compensate for potential recognition processing failures. If recognition processing fails or produces abnormal results, the system has pre-configured fallback options to maintain stable video display without interruption.
Solution Approach 2:
The system introduces an intermediary control mechanism that monitors recognition processing output and mediates between the recognition processing module and the display system. This intermediary detects abnormal results and coordinates the switching to backup pathways, ensuring smooth transitions and maintaining display stability.
3Reliability
If the system switches between first video signals and second video signals based on recognition processing status, then video display stability is improved, but device complexity increases
Solution Approach 1:
The system combines the switching control logic with the existing video signal processing pathway, integrating the selection between first and second video signals into the current signal routing infrastructure. This merging approach minimizes additional complexity by reusing existing system components and control mechanisms.
Solution Approach 2:
The processor switching mechanism is designed to handle multiple functions: normal video display, recognition processing output display, error handling, and fallback operations. This multi-functionality reduces the need for separate dedicated switching circuits for each function, thereby reducing overall device complexity.
Data Source
AI summary
An endoscope processor device generates first video signals. A recognition processing processor device generates second video signals by reflecting a result of recognition processing based on the first video signals. A display displays any one of the second video signals or the first video signals switched from the second video signals on the basis of first video switching signals from the recognition processing processor device. The display displays that a result display of the recognition processing is being stopped in a case where the result display of the recognition processing by the second video signals is stopped.
