Needle Biopsy Image Display Area Navigation via Center Line Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for viewing needle biopsy images allow excessive user freedom in navigation, making it difficult to adequately move the display area along the elongated specimen, which hinders focused diagnosis.
Innovation Solution
An information processing apparatus that uses guide information along the center line of the specimen's shape to determine the range of the observation image, allowing users to input rough instructions for scrolling, with the system calculating the precise range based on this information, and includes features like guide modes, prefetching, and tilt sensor input for intuitive navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional browsing method is used, then user has excessive freedom in navigation, but it becomes difficult to adequately move display area along elongated specimen
Solution Approach 1:
The patent introduces guide information as an intermediary element between the user's navigation intent and the actual display area movement. The guide information includes guide lines and guide points that mediate the relationship, translating rough user instructions into precise movements along the specimen's center line while maintaining ease of operation.
Solution Approach 2:
The system provides visual feedback through guide lines and guide points that dynamically adjust as the user navigates. The display control unit outputs guide information based on the current observation image position, creating a feedback loop that ensures accurate movement along the specimen while maintaining user freedom in navigation direction.
2Ease of operation
If user manually adjusts scroll direction, then can control observation range, but increases user effort and reduces diagnosis focus
Solution Approach 1:
The system performs self-service by automatically calculating the observation range based on guide information and user input. The control unit autonomously determines the appropriate scroll direction and distance along the specimen's center line, eliminating the need for users to manually adjust scroll direction and reducing their effort while maintaining control over the observation range.
Solution Approach 2:
The guide information is pre-calculated and stored before actual navigation occurs. The storage unit stores guide information including guide lines and guide points that are prepared in advance, allowing the system to quickly determine the observation range without requiring users to perform preliminary manual adjustment of scroll direction.
3Measurement precision
If guide information is added to the system, then display area movement accuracy improves, but device complexity increases
Solution Approach 1:
The guide information is segmented into discrete guide points and guide lines that are stored separately from the main image data. The storage unit stores guide information in a structured format that can be independently accessed and processed, allowing the system to maintain high position accuracy while managing complexity through modular organization of guide data.
Solution Approach 2:
The guide information serves multiple functions: it defines the observation range, provides scroll direction guidance, and enables automatic positioning. By making the guide information multi-functional, the system achieves high measurement precision without proportionally increasing device complexity, as the same data structure serves multiple navigation purposes.
