Scan Protocol Mapping via Keyword Scoring Algorithm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current scan protocols lack standardization across different countries and institutions, making it difficult to compare and establish national or international registries, particularly in radiology, where manual mapping of protocols is cumbersome and time-consuming.
Innovation Solution
A method for mapping user-created scan protocols to standardized protocols using a keyword scoring algorithm, which extracts textual parameters, generates a combined dataset, determines keyword scores, and selects the most relevant standardized protocol from a database like RadLex playbook, facilitating harmonization and consistency across institutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual mapping of scan protocols is performed, then mapping accuracy can be maintained, but time consumption and labor costs increase significantly
Solution Approach 1:
The patent introduces an automated mapping system that acts as an intermediary between scan protocols and standardized protocols. This system uses natural language processing and keyword scoring algorithms to automatically extract meaningful parameters from protocol names and descriptions, generating mapping suggestions that reduce manual work while maintaining accuracy through radiologist review.
Solution Approach 2:
The patent replaces the manual mechanical process of protocol mapping with an automated computational system. The system uses text analysis algorithms, keyword scoring, and database matching to automatically generate mapping recommendations, substituting human manual effort with automated information processing while maintaining quality through hybrid human-machine verification.
2Adaptability or versatility
If standardized scan protocols are implemented across institutions, then comparability and registry establishment improve, but implementation complexity and standardization requirements increase
Solution Approach 1:
The patent creates a universal mapping system that can handle multiple types of scan protocols from different institutions and modalities. The system uses a standardized protocol database (RadLex) that serves as a common reference framework, allowing diverse local protocols to be mapped to universal standards, enabling cross-institutional comparability without requiring each institution to develop their own standards.
Solution Approach 2:
The patent transforms protocol information from unstandardized local formats to standardized formats by changing key parameters such as protocol naming conventions, anatomical region classifications, and modality descriptors. The system identifies and standardizes these critical parameters while preserving essential local variations, reducing implementation complexity through focused parameter standardization rather than complete protocol replacement.
3Productivity
If automated mapping systems are used, then time efficiency improves, but mapping precision and reliability may deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where automated mapping suggestions are presented to radiologists for review and confirmation. The system learns from radiologist corrections and feedback, continuously improving its mapping accuracy. This hybrid approach maintains high productivity through automation while ensuring reliability through human expertise validation, creating a self-improving system that combines the speed of automation with the judgment of specialists.
