Processor Device Index Value Narrowing for Endoscope Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In endoscopic diagnosis, the analysis efficiency of index values for vascular patterns is reduced due to unnecessary index values being included, leading to wasted inspection time, as current methods do not effectively narrow down the required index values for lesion diagnosis.
Innovation Solution
A processor device with an image acquisition unit, index value calculation unit, processing order storage unit, and index value arithmetic processing unit that controls the calculation and determination of index values based on a preset processing order, allowing for the selection and display of only the necessary index values required for diagnosis, utilizing a combination of image processing and medical knowledge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple index values are calculated for comprehensive lesion diagnosis, then diagnostic accuracy is improved, but analysis efficiency is reduced and inspection time is wasted
Solution Approach 1:
The system dynamically adjusts the set of index values to be calculated based on the results of previous index value determinations. The processing order storage unit stores multiple processing orders, and the system selects and executes appropriate processing orders dynamically according to the specific lesion characteristics observed, thereby optimizing the balance between diagnostic accuracy and analysis efficiency for each case
Solution Approach 2:
Different index values are determined with different priorities and levels of detail based on the specific diagnostic needs. The system identifies which index values are most relevant to the current lesion type and focuses computational resources on determining those specific index values with high precision, rather than uniformly processing all index values
2Reliability
If multiple index values are calculated for comprehensive lesion diagnosis, then diagnostic coverage is improved, but inspection time is increased
Solution Approach 1:
The system performs preliminary determination of index values in a predetermined processing order before proceeding to more time-consuming calculations. By establishing the processing order in advance and performing initial index value determinations first, the system can identify early on which additional index values are truly necessary, avoiding unnecessary computational time
Solution Approach 2:
The processing order is dynamically adjusted based on intermediate results. As the system determines index values sequentially, it can modify the remaining processing order to skip unnecessary calculations or prioritize critical ones, thereby reducing total inspection time while maintaining comprehensive diagnostic coverage
3Reliability
If all index values are processed to ensure complete lesion characterization, then diagnostic completeness is improved, but analysis complexity is increased
Solution Approach 1:
The comprehensive set of index values is segmented into different processing groups with different levels of priority and computational complexity. The system processes index values in segments according to the stored processing orders, handling critical index values first and optional index values later, thereby managing analysis complexity while ensuring diagnostic completeness
