Solution Overview
Problem
Existing ultrasonic diagnosis systems face challenges in continuously observing virtual endoscopic image data in real time as the ultrasonic probe moves, requiring complex processes to update the viewpoint and view direction for generating virtual endoscopic image data based on volume data acquired from organs like small alimentary canals and blood vessels.

An ultrasonic diagnosis system that includes a region-of-interest setting unit, center line setting unit, reference point detecting unit, viewpoint/view-direction setting unit, and virtual endoscopic image data generating unit, which automatically sets and updates the viewpoint and view direction based on the intersection of a reference plane and center line within the volume data, allowing continuous observation of virtual endoscopic image data in real time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the conventional method of setting viewpoint and view direction based on MPR image data is used, then virtual endoscopic image data can be generated, but the process becomes complicated and cannot be updated in real time when the ultrasonic probe moves
Solution Approach 1:
The system automatically determines the viewpoint and view direction based on the ultrasonic probe's position and orientation, without requiring manual intervention. The control unit self-adjusts the virtual endoscopic parameters by detecting probe movement and recalculating the viewpoint and view direction accordingly, enabling real-time updates without complex manual processes
Solution Approach 2:
The system continuously monitors the ultrasonic probe's position and orientation during movement, and uses this feedback information to dynamically adjust the viewpoint and view direction for virtual endoscopic image generation. This closed-loop control enables real-time observation by automatically updating the virtual endoscopic parameters based on current probe state
2Adaptability or versatility
If the ultrasonic probe moves on the body surface to continuously observe the organ, then more comprehensive examination is possible, but the viewpoint and view direction must be repeatedly updated which prevents real-time observation
Solution Approach 1:
The system dynamically adjusts the viewpoint and view direction in response to probe movement. The control unit continuously tracks changes in probe position and orientation, and automatically updates the virtual endoscopic parameters to maintain appropriate viewing angles, enabling real-time adaptation as the probe moves across different body surface positions
Solution Approach 2:
The system pre-establishes the relationship between probe position/orientation and virtual endoscopic viewpoint/view direction through automated calculation algorithms. When the probe moves to a new position, the system has already prepared the transformation rules to quickly determine the new viewpoint and view direction, eliminating the need for time-consuming manual adjustments
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables constant and precise observation of virtual endoscopic image data in real time even as the ultrasonic probe moves, improving diagnostic precision and efficiency by reducing the need for repetitive processes and maintaining a stable reference point on the monitor.
Implementation Method 1
The ultrasonic pulse is generated in an oscillating element in an ultrasonic probe
Implementation Method 2
acquires biological information by emitting an ultrasonic pulse and receiving a reflected ultrasonic wave from the object tissue. The reflected ultrasonic wave depends on the acoustic impedance in the object tissue

AI summary
An ultrasonic diagnosis system that generates virtual endoscopic image data on a lumen of an organ of an object based on volume data acquired by three-dimensional scanning of the object, includes: a unit that sets a three-dimensional region of interest for the volume data; a unit that sets a center line of the lumen of the organ in the volume data based on the acquired volume data; a unit that detects a reference point at which a reference plane of the three-dimensional region of interest and the center line intersect with each other; a unit that sets a viewpoint and a view direction based on the reference point; a virtual endoscopic image data generating unit that processes the volume data based on the viewpoint and the view direction to generate the virtual endoscopic image data; and a display unit that displays the generated virtual endoscopic image data.
