Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blood flow rate imaging devices struggle to accurately distinguish between surface layer blood vessels and background blood flow, particularly in regions with meandering vessels, and fail to effectively measure blood vessel diameters due to noise and limited sample sizes, leading to difficulties in analyzing blood flow waveforms and circulatory functions.
Innovation Solution
A blood flow image diagnosis device that separates surface layer blood vessels from background blood flow using advanced image processing techniques, including disparity compensation, mask creation, and feature extraction, allowing for the calculation and display of blood vessel diameters and waveforms, enabling clearer visualization and analysis of blood flow patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional blood flow rate imaging is used to measure blood flow in body tissue, then blood flow distribution can be visualized, but the images are grainy and cannot accurately distinguish surface layer blood vessels from background blood flow
Solution Approach 1:
The patent applies segmentation by separating blood flow signals into two distinct components: surface layer blood vessel blood flow and background blood flow. This is achieved through mathematical decomposition of the blood flow rate data, allowing each component to be analyzed independently and displayed separately, thereby resolving the graininess issue and enabling accurate distinction between vessel and background regions.
2Reliability
If statistical error is reduced by increasing sample size, then measurement reliability improves, but the complexity of processing sequential blood flow maps increases
Solution Approach 1:
The patent extracts the essential blood flow information by separating and isolating the surface layer blood vessel component from the complex sequential blood flow maps. This extraction process focuses computational resources on the relevant signal components, reducing the effective processing complexity while maintaining high measurement reliability through targeted analysis of separated blood flow components.

AI summary
A blood flow image diagnosis device which diagnoses a blood flow map by separating, on the basis of a plurality of blood flow maps covering a specified time including one or more cardiac beats, a blood flow of a surface layer blood vessel observed in a surface layer in an observation region of a body tissue from a background blood flow of a peripheral background region. The device distinguishably displays a first blood flow map of the surface layer blood vessel and a second blood flow map of the background blood flow. The device calculates and compares information on a blood flow including blood flow value, blood flow waveform, or blood vessel diameter in the first and second blood flow maps, and displays the calculated information.
