Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple CAD algorithms are applied to image datasets to detect different ailments, then detection coverage is improved, but system complexity and processing time increase
Solution Approach 1:
The system changes the parameter of algorithm selection by using IHE-WL worklist data to dynamically determine which CAD algorithms should be applied based on patient-specific diagnostic procedures. This allows the system to adapt detection coverage to clinical needs without permanently increasing system complexity, as algorithms are selected conditionally rather than being always active.
Solution Approach 2:
The system segments the overall CAD processing into distinct algorithm modules that can be independently selected and executed. Each CAD algorithm operates as a separate functional unit that can be activated based on worklist information, allowing the system to manage complexity by organizing algorithms into discrete, selectable components rather than a monolithic processing system.
2Measurement precision
If CAD systems manually select algorithms based on patient data, then analysis accuracy is improved, but processing time and operational complexity increase
Solution Approach 1:
The system implements self-service automation where the CAD system automatically queries the RIS for IHE-WL worklist data, analyzes the diagnostic procedures, and selects appropriate algorithms without requiring manual intervention. The system serves itself by autonomously determining algorithm selection based on worklist information, eliminating the need for manual algorithm selection while maintaining analysis accuracy.
Solution Approach 2:
The system performs preliminary action by querying the RIS for worklist data before executing CAD algorithms. By obtaining diagnostic procedure information in advance from the worklist, the system can pre-determine which algorithms to apply, avoiding the need for manual selection during the analysis phase and reducing overall processing time.
3Measurement precision
If CAD systems integrate with RIS and PACS to access patient data, then diagnostic precision is improved, but system integration complexity increases
Solution Approach 1:
The system utilizes the universal IHE-WL worklist standard that is already implemented in RIS and PACS systems. By leveraging this existing multi-functional interface that is commonly present in healthcare information systems, the CAD system can access patient data and diagnostic procedures without requiring complex custom integration, as the worklist provides a standardized entry point to multiple data sources.
Solution Approach 2:
The IHE-WL worklist serves as an intermediary that mediates between the CAD system and the RIS/PACS infrastructure. Rather than the CAD system directly integrating with multiple complex systems, it uses the worklist as an intermediate data source that already contains aggregated patient information and diagnostic procedures, simplifying the integration architecture.
4Productivity
If automated algorithm selection is implemented using IHE-WL, then productivity is improved, but reliance on standardized codes and systems is required
Solution Approach 1:
The system achieves both productivity improvement and adaptability by using the universal IHE-WL worklist standard that is widely adopted across healthcare systems. This standardized interface maintains system flexibility by working with existing RIS and PACS infrastructures while enabling automated algorithm selection that improves processing efficiency. The worklist's multi-functional nature allows it to serve both as a productivity-enabling automation source and as a flexible adapter to various healthcare information systems.

AI summary
A computer implemented method for automatically selecting an algorithm for image analysis in a computer-aided detection/diagnosis (CAD) system includes receiving image data for a study involving a patient, querying a radiology information system (RIS) for an IHE (Integrating the Healthcare Enterprise)-worklist for the study of the patient, receiving the IHE-worklist from the RIS, analyzing the worklist to select one or more CAD algorithm for analyzing the image data, executing the selected one or more CAD algorithms to analyze the image data, and outputting results of the analysis of the image data.
