Medical Information Processing Apparatus Blood Flow Graph Orientation Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical information processing systems face challenges in effectively displaying blood flow index graphs, particularly due to differences in display orientation between fluid analysis and pressure wire measurement methods, which can reduce visibility and familiarity for operators.
Innovation Solution
A medical information processing apparatus that acquires and processes CT image data to calculate blood flow indices, such as FFR, and adjusts the display orientation based on external information like location, operator, and image data, ensuring alignment with familiar graph orientations to improve visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fluid analysis is performed based on CT image data to calculate blood flow indices, then non-invasive evaluation of hematogenous ischemia is achieved, but the display orientation of the resulting graphs differs from conventional pressure wire measurement methods, reducing operator familiarity and visibility
Solution Approach 1:
The patent inverts the conventional display orientation approach by making the fluid analysis graph orientation conform to the established pressure wire measurement display standards, rather than forcing operators to adapt to new display conventions. This is achieved by transforming the graph data and reorienting it to match conventional medical display practices, thereby maintaining operator familiarity while enabling non-invasive evaluation.
Solution Approach 2:
The patent creates a copy of the conventional pressure wire measurement display format and applies it to the fluid analysis results. By replicating the familiar graph orientation, axis arrangements, and visual presentation styles from pressure wire measurements, the system allows operators to interpret fluid analysis data using their existing expertise, thus improving ease of operation without sacrificing the non-invasive advantage.
2Loss of information
If multiple types of medical information are integrated and displayed together, then comprehensive diagnostic information is provided, but the complexity of information processing and display management increases
Solution Approach 1:
The patent merges multiple types of medical information (fluid analysis results, CT image data, and external information) into a unified display framework. By integrating these diverse data sources into a single coherent graphical representation with standardized orientation, the system provides comprehensive diagnostic information while managing processing complexity through a unified approach rather than separate handling of each data type.
Solution Approach 2:
The patent creates a universal display system that can handle multiple types of medical information using the same processing and presentation framework. The graph display mechanism is designed to accommodate different data sources and types while maintaining consistent orientation and formatting, thereby reducing the complexity that would arise from implementing separate processing systems for each information type.

AI summary
A medical information processing apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires a first index value obtained based on fluid analysis that is performed based on an image including a blood vessel of a subject, the first index value being related to blood flow at each of positions in the blood vessel. The processing circuitry acquires external information including a second index value related to blood flow at each of the positions in the blood vessel. The processing circuitry changes one of an arrangement direction of index values in a first graph and an arrangement direction of index values in a second graph in accordance with the other one of the arrangement directions. The processing circuitry displays the first graph and the second graph on a display unit such that the arrangement directions of the index values match each other.
