Solution Overview
Problem
Current medical image diagnosis methods for cardiac regions require separate analysis and interpretation of cardiac function and myocardial infarction, making it difficult to accurately determine if myocardial infarction is present in areas with deteriorated cardiac function.
Innovation Solution
A medical image diagnosis assisting apparatus and method that calculates cardiac function evaluation values and myocardial infarction rates from three-dimensional medical images and outputs a superimposed image, allowing clear visualization of these values in a coordinate system to distinguish between angina pectoris and myocardial infarction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate analysis methods are used for cardiac function and myocardial infarction, then each analysis can be performed independently, but it becomes difficult to accurately determine the positional relationship between the two analyses
Solution Approach 1:
The patent merges separate cardiac function analysis and myocardial infarction analysis into a single integrated analysis system. The image processing apparatus performs both analyses simultaneously on the same three-dimensional medical image data, automatically determining positional relationships and presenting unified diagnostic information, thereby eliminating the information loss that occurs when analyses are performed separately.
2Ease of operation
If doctors manually imagine the correspondence relationship between separate analyses, then overall judgment can be made, but the process becomes complex and error-prone
Solution Approach 1:
The system performs self-service by automatically calculating and determining the positional relationships between cardiac function and myocardial infarction analyses. The image processing apparatus autonomously processes the three-dimensional medical image data, computes both analyses, and generates integrated results without requiring doctors to manually imagine or calculate correspondences, thereby improving both ease of operation and reliability.
3Loss of information
If multiple separate analyses are performed, then comprehensive diagnostic information can be obtained, but the time required for diagnosis increases
Solution Approach 1:
The patent implements continuous useful action by performing cardiac function analysis and myocardial infarction analysis in an integrated, simultaneous process. The image processing apparatus processes the three-dimensional medical image data through both analytical pathways concurrently, generating comprehensive diagnostic information in a single operation rather than through sequential separate analyses, thereby reducing diagnosis time while maintaining information completeness.

AI summary
Using a three-dimensional medical image representing a heart as input, a cardiac function analysis unit calculates a cardiac function evaluation value representing a cardiac function with respect to each of predetermined portions of the heart, using a three-dimensional medical image representing the heart as input, a myocardial infarction analysis unit calculates a myocardial infarction rate representing a degree of myocardial infarction with respect to each of predetermined portions of the heart, and a superimposed image output unit outputs a superimposed image representing the cardiac function evaluation value and the myocardial infarction rate in a superimposing manner such that they are distinguishable from each other in a coordinate system capable of representing each position of the heart in the three-dimensional medical image.
