Solution Overview
Problem
Current medical image processing systems for cardiac diseases present multiple types of information, such as Wall Shear Stress (WSS) and Fractional Flow Reserve (FFR), without restriction, making it complicated for users to understand and make decisions during diagnosis and treatment planning.
Innovation Solution
A medical image processing apparatus that extracts a disease degree from medical images and selectively displays either FFR or WSS based on the disease severity, switching between these indices to simplify user interaction and improve decision-making during cardiac disease diagnosis and treatment planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple types of information (WSS, FFR, etc.) are presented without restriction, then the comprehensiveness of diagnostic information is improved, but the complexity of user work and understanding increases
Solution Approach 1:
The system dynamically changes the display parameter (type of blood flow information) based on the extracted disease degree. When disease degree is high, FFR is displayed; when low, WSS is displayed. This parameter switching resolves the contradiction by adapting the information presentation to the specific clinical context.
Solution Approach 2:
The display content is made dynamic rather than static. The system automatically adjusts which blood flow information is displayed based on the extracted disease degree, transforming the fixed multi-information display into a flexible, condition-based display that reduces user complexity while maintaining comprehensiveness.
2Measurement precision
If multiple types of information are presented without restriction, then the accuracy of diagnosis is improved, but the time required to obtain and understand information increases
Solution Approach 1:
The system performs preliminary action by automatically extracting the disease degree and pre-selecting the appropriate blood flow information (FFR or WSS) before the user needs to make a diagnosis. This eliminates the time required for users to manually evaluate multiple information types, while still providing accurate diagnostic data.
Solution Approach 2:
The system extracts and displays only the relevant blood flow information based on the disease degree, taking out the unnecessary information from the complete set. This extraction approach maintains diagnostic accuracy by providing the most appropriate information while reducing the time needed to process information.
3Adaptability or versatility
If all blood flow information is displayed simultaneously, then the versatility of the diagnostic system is improved, but the ease of operation decreases
Solution Approach 1:
The system performs self-service by automatically determining which blood flow information to display based on the extracted disease degree, without requiring user intervention to select or filter information. This maintains the versatility of the system while significantly improving ease of operation, as users simply view the appropriately selected information.

AI summary
A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to extract a degree of a disease related to the heart from a medical image; and display, when the degree of the disease related to the heart is high, a first index value related to a blood vessel and calculated from one of blood pressure and a blood flow and configured to display, when the degree of the disease related to the heart is low, wall shear stress serving as a second index value related to the blood vessel, as information related to the blood flow of the blood vessel and calculated on the basis of the medical image.
