Ultrasonic Imaging Region of Interest Centering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ultrasonic imaging systems require significant time and labor to achieve a balanced stereoscopic display of massive tissue surfaces, as the boundary of the massive tissue may not be well-centered within the 3D region of interest, leading to incomplete stereoscopic displays.
Innovation Solution
An ultrasonic imaging apparatus that includes a 3D tomographic image data capturing device, a region-of-interest setting device allowing manual marker placement for a 2D region of interest, and a 3D region-of-interest generating device that expands the 2D region orthogonally to center the massive tissue boundary, ensuring it spans the entire 3D region of interest for optimal stereoscopic display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a 2D region of interest is manually set by forming a borderline using a cursor, then the operator can specify the massive tissue region, but the boundary may not be well-centered in the 3D region of interest, resulting in incomplete stereoscopic display
Solution Approach 1:
The system automatically expands the 2D region of interest borderline into a 3D region of interest before the operator completes the manual setting process. This preliminary expansion ensures that the massive tissue boundary is well-centered in the 3D region, eliminating the need for repeated adjustments and ensuring complete stereoscopic display coverage.
2Manufacturing precision
If the operator repeatedly sets the 2D region of interest to maximize the spread of the boundary, then the stereoscopic display can cover the entire 3D region, but it takes much time and labor
Solution Approach 1:
The automatic expansion of the 2D region of interest borderline into a 3D region of interest is performed preliminarily during the setting process. This ensures that the stereoscopic display coverage is maximized from the beginning, eliminating the need for repeated adjustments and significantly reducing the time and labor required.
Solution Approach 2:
The system automatically adjusts the 3D region of interest based on the 2D borderline input, performing the expansion operation itself without requiring repeated manual intervention. This self-service capability ensures optimal coverage while minimizing operator effort and time investment.
3Productivity
If the boundary falls outside the automatically expanded 3D region of interest, then the stereoscopic display is limited to a small part of the region, but the operator cannot easily adjust without repeating the setting process
Solution Approach 1:
The 3D region of interest is automatically expanded to include the massive tissue boundary before the operator completes the manual setting. This preliminary action ensures that the boundary is always within the 3D region, eliminating the need for repeated adjustments and enabling quick obtaining of the stereoscopic display.

AI summary
An ultrasonic imaging apparatus includes a 3D tomographic image data capturing device which captures 3D tomographic image data from a 3D region inside a subject, a region-of-interest setting device which sets a 3D region of interest corresponding to the 3D region in an image memory, a surface image extracting device which extracts data on a surface image, in the 3D region of interest, of a massive tissue included in the 3D region, a stereoscopic display generating device which generates stereoscopic display data, and a display device which displays the stereoscopic display data. The region-of-interest setting device displays a 2D tomographic image of a 2D region including the massive tissue on the display device, allows setting of a marker indicating a periphery of the massive tissue in the 2D tomographic image, and generates the 3D region of interest according to data on the marker's position.
