3D Tissue Imaging With Lumen Cutaway and Cross-Section Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasound imaging systems struggle to generate accurate three-dimensional images of cardiac cavities and blood vessels, requiring manual reconstruction by operators, which can be challenging for inexperienced doctors, and lack visibility into the inner structures of biological tissues.
Innovation Solution
An image processing device that automatically generates three-dimensional data of biological tissues, forms a cutting region to expose the lumen, and displays a corresponding two-dimensional image on a cross-section, updating in real-time with new tomographic data to provide supplementary information on the cut-out region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a three-dimensional image is generated from two-dimensional IVUS images, then the structure of biological tissue can be visualized, but the lumen cannot be seen because only the outer wall of the tissue is displayed
Solution Approach 1:
The patent extracts and removes a portion of the biological tissue structure from the three-dimensional image data to create a cutting region. This extraction allows the lumen, which was previously obscured by the tissue structure, to become visible while maintaining the overall three-dimensional visualization capability
2Ease of operation
If the cutting region is formed to expose the lumen, then the lumen becomes visible, but information about the cut-out region is lost making it difficult to grasp the operator's position
Solution Approach 1:
The patent introduces a two-dimensional image as an intermediary element that supplements the three-dimensional image. This two-dimensional image displays the cut surface of the biological tissue at the cutting region, providing spatial orientation information and helping the operator understand their position within the tissue structure
Solution Approach 2:
The patent transitions from a purely three-dimensional visualization to a combined two-dimensional and three-dimensional display system. By adding the two-dimensional cross-sectional view, the system provides additional spatial information that complements the three-dimensional image and resolves the information loss caused by the cutting region
3Measurement precision
If manual reconstruction of three-dimensional structure is performed by operators, then three-dimensional visualization is achieved, but the process becomes complex and challenging for inexperienced doctors
Solution Approach 1:
The patent implements automatic generation of the three-dimensional image and automatic formation of the cutting region by the image processing device itself. This self-service capability eliminates the need for manual reconstruction operations by the operator, reducing operational complexity while maintaining high accuracy in the three-dimensional structure visualization

AI summary
An image processing device is an image processing device that causes a display to display, as a three-dimensional image, three-dimensional data representing a biological tissue. The image processing device includes: a control unit configured to form, in the three-dimensional data, a cutting region for exposing a lumen of the biological tissue in the three-dimensional image, and to display, on the display, a two-dimensional image representing a portion corresponding to the cutting region in one cross section of the biological tissue at a position corresponding to the one cross section in the three-dimensional image.
