Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If AI algorithms are integrated into clinical workflows, then cancer detection accuracy and diagnostic efficiency are improved, but algorithm selection complexity and system integration requirements increase
Solution Approach 1:
The system segments the AI algorithm selection process into distinct modules: use case identification module, anatomical object determination module, and algorithm selection module. Each module handles a specific aspect of the complex selection process independently, making the overall system more manageable and easier to implement while maintaining high detection accuracy through specialized algorithm application.
2Adaptability or versatility
If multiple AI algorithms are applied to different anatomical objects, then comprehensive clinical assessment is improved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary actions by pre-categorizing anatomical objects and pre-selecting appropriate algorithms based on use case scenarios. The anatomical object determination module identifies the relevant anatomical structures before algorithm execution, and the algorithm selection module retrieves pre-validated algorithms matching the anatomical category, significantly reducing processing time while maintaining comprehensive assessment coverage.
3Measurement precision
If AI algorithms are made more specialized for specific anatomical objects, then diagnostic precision for specific structures is improved, but system versatility and adaptability decrease
Solution Approach 1:
The system achieves universality by creating a modular architecture where the same framework can handle multiple anatomical objects through a unified algorithm selection mechanism. The anatomical object determination module and algorithm selection module work together to adapt specialized algorithms to different anatomical contexts, allowing the system to maintain high diagnostic precision for specific structures while remaining versatile across various anatomical regions and disease types.

AI summary
A system (100) for processing medical image data regarding a clinical question uses patient data (110), medical image data (120) and clinical guidelines (170). The system has a processor subsystem (160) to determine, based on user input (140), a use case regarding the clinical question for a patient. The processor retrieves the patient data and image data regarding the use case to determine an anatomical object. Then, the processor selects an algorithm from an algorithm repository (AM) based on the determined anatomical object and executes the algorithm on the image data to provide the output data for assessing the clinical question. The processor may also use the codified clinical guidelines regarding the use case to select said algorithm. Effectively the most appropriate algorithm is executed for the specific use case.
