Medical Document Comparison via Corresponding Description Highlighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating medical interpretation reports do not effectively allow for easy comparison between reports of different creation times, limiting the ability to analyze changes or developments in patient conditions over time.
Innovation Solution
An information processing apparatus and method that acquires multiple medical documents with different creation times, specifies corresponding descriptions, and displays them differently to facilitate comparison, including highlighting key differences and lesion-specific information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple medical documents are displayed without special formatting, then the display is simple and clear, but it becomes difficult to compare corresponding descriptions between documents with different creation times
Solution Approach 1:
The patent applies color changes by displaying corresponding descriptions in different colors or with different background shades to highlight similarities and differences between medical documents. When a user selects a description in one document, the system automatically highlights the corresponding description in another document using color coding, making it easy to compare temporal changes in medical records without complex interfaces.
Solution Approach 2:
The patent implements local quality by applying visual differentiation only to specific corresponding descriptions rather than the entire document. When a user selects a particular description, only that description and its counterpart in another document are highlighted with special formatting, while the rest of the document maintains normal display. This localized approach enables easy comparison of specific medical findings across time points without overwhelming the user with global document changes.
2Loss of information
If all descriptions in medical documents are displayed uniformly, then the display process is simple, but it becomes difficult to identify key differences and changes over time
Solution Approach 1:
The patent uses color changes to preserve all information while enhancing identifiability. All descriptions are displayed uniformly in the base state, but when comparison is needed, the system selectively applies color highlighting to corresponding descriptions. This ensures no information is lost in the uniform display mode while enabling easy identification of key differences through color-coded highlights when comparison functionality is activated.
Solution Approach 2:
The patent implements dynamics by making the display format adaptable based on user interaction. Descriptions are displayed uniformly by default, but upon user selection of a specific description, the system dynamically transforms the display to highlight corresponding descriptions in other documents. This dynamic switching between uniform and differentiated display modes allows the system to preserve information completeness while enabling easy identification of changes when needed.
3Productivity
If the system highlights all corresponding descriptions automatically, then comparison is facilitated, but it increases processing complexity and computation time
Solution Approach 1:
The patent applies preliminary action by pre-processing medical documents to identify and store corresponding descriptions between documents with different creation times. The system analyzes document structures, identifies semantic equivalences, and creates a mapping database of corresponding descriptions in advance. This preliminary processing enables rapid comparison when users interact with the system, as the heavy lifting of identifying correspondences has already been completed during document ingestion rather than during user interaction.
Solution Approach 2:
The patent uses copying by creating and maintaining a replicated structure of description correspondences between medical documents. Instead of performing complex real-time analysis when users request comparison, the system has already copied and stored the relational structure of corresponding descriptions during initial document processing. This pre-copied structural information allows the system to quickly retrieve and highlight corresponding descriptions without complex processing during user interaction.

AI summary
A processor is configured to: acquire a plurality of medical documents having different creation times; specify mutually corresponding descriptions in each of one medical document among the plurality of medical documents and at least one other medical document other than the one medical document; display the one medical document on a display; receive designation of a character string for the one medical document; and display a description of the at least one other medical document corresponding to a description including the designated character string in a manner different from other descriptions other than the description corresponding to the description including the designated character string.
