Solution Overview
Problem
Existing ultrasonic diagnostic techniques fail to form continuous streamlines indicating fluid flow, as they only display streamlines downstream from the initial start point, resulting in interrupted and unnatural representations.
Innovation Solution
An ultrasonic diagnostic device that includes a probe, transmitter and receiver unit, Doppler processing unit, vector computation unit, and streamline forming unit, which inversely tracks fluid flow from an initial start point to search for a proper start point upstream, forming a continuous streamline extending from this point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If streamline is formed only downstream from the initial start point, then the processing is simple, but the streamline appears interrupted and unnatural
Solution Approach 1:
The patent applies inverse tracking by calculating streamlines in the direction opposite to the flow direction. Instead of only tracking downstream from the start point, the system traces upstream to find the proper start point, then forms the complete streamline extending in both directions. This inversion approach resolves the contradiction by maintaining processing simplicity while achieving continuous, natural streamline representation.
2Reliability
If inverse tracking is performed to find proper start point upstream, then continuous streamlines are formed, but the processing complexity increases
Solution Approach 1:
The patent implements inverse tracking by reversing the flow direction calculation to trace upstream from the initial start point. This allows the system to locate the proper start point and form continuous streamlines without requiring fundamentally new processing methods, thus achieving streamline continuity with minimal increase in processing complexity.
Solution Approach 2:
The system performs preliminary inverse tracking to identify the proper start point before forming the complete streamline. By pre-determining the optimal start location through upstream tracking, the subsequent streamline formation becomes more efficient and organized, reducing overall processing complexity while maintaining continuity.

AI summary
An ultrasonic diagnostic device wherein: a Doppler processing unit acquires Doppler information in a living body on the basis of an ultrasonic reception signal; a velocity vector calculating unit acquires the velocity vector distribution of a blood stream in the living body on the basis of the Doppler information in the living body; and, to form a flow line showing the flow of the blood stream on the basis of the velocity vector distribution, a flow line forming unit searches for a proper start point by inversely tracing the flow of the blood stream from an initial start point along the reverse direction of the velocity vector and then forms a flow line extended from the proper start point.
