3D Tissue Imaging With Virtual Opening for Inner Wall Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasound-based imaging techniques, such as IVUS, generate two-dimensional images that require manual reconstruction to form a three-dimensional view, posing a challenge for inexperienced operators, especially when visualizing the interior of biological tissues like cardiac cavities or blood vessels.
Innovation Solution
A diagnostic assistance device that generates three-dimensional data from tomographic data and displays it with an opening exposing the inner wall surface, allowing adjustment of the viewpoint based on the opening's position to facilitate interior visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic three-dimensional image generation from IVUS data is implemented, then the barrier for young or inexperienced doctors is removed and ease of operation is improved, but the ability to visualize the inside of biological tissue is lost because only the outer wall is visible
Solution Approach 1:
The patent extracts the inner wall surface information from the three-dimensional data by forming a virtual opening that removes the outer wall obstruction. This allows the inner wall surface to be visualized separately while maintaining the overall three-dimensional structure, thus extracting the critical internal information that was previously hidden.
Solution Approach 2:
The patent transitions from a standard external three-dimensional view to an internal visualization by creating a virtual opening. This dimensional transformation allows the inner wall surface to be observed from within the biological tissue structure, providing a new perspective that reveals internal features while maintaining three-dimensional context.
2Device complexity
If a standard three-dimensional image is generated showing only the outer wall, then the imaging process is simple and device complexity is reduced, but the operator cannot perform treatment inside the biological tissue due to lack of internal visualization
Solution Approach 1:
The patent introduces dynamic control over the three-dimensional image display by allowing the opening position and viewpoint to be adjusted based on treatment requirements. This dynamic adaptability enables the system to transition between different visualization modes (external view, internal view, cross-sectional views) without requiring multiple separate devices or complex hardware changes.
Solution Approach 2:
The patent makes the three-dimensional imaging system universal by enabling it to perform multiple functions: external surface visualization, internal structure visualization through virtual openings, and cross-sectional imaging. This multi-functionality is achieved through software-based processing that can adapt the same three-dimensional data to different visualization needs, eliminating the need for separate specialized devices.

AI summary
A diagnostic assistance device is a diagnostic assistance device configured to generate three-dimensional data of a biological tissue based on tomographic data of the biological tissue, and display the generated three-dimensional data as a three-dimensional image on a display. The diagnostic assistance device includes a control unit configured to form, in the three-dimensional data, an opening that exposes an inner wall surface of the biological tissue to an outside of the biological tissue in the three-dimensional image, and adjust a viewpoint when displaying the three-dimensional image on the display according to a position of the formed opening.
