Side Viewpoint Rendering for Surgical Cut Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image-guided surgery systems face limitations in providing a clear view of anatomical structures during procedures, especially in narrow anatomical passageways, as they require manual adjustment of viewpoints to visualize critical areas effectively.
Innovation Solution
An image processing device and method that allows for the simple operation to generate and display a side viewpoint image of a cut section in a three-dimensional organ model, enabling easy visualization of internal structures by setting a cut section and deriving a viewpoint intersecting its normal line, thereby enhancing usability and clarity during surgical simulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a virtual camera is used to provide a view of the 3D model in image-guided surgery systems, then the visualization of anatomical structures is improved, but the ability to view cut sections from optimal angles is limited when the surgical instrument is in narrow anatomical passageways
Solution Approach 1:
The system pre-calculates and stores optimal viewpoint information for each cut section before surgery. When a cut section is selected during surgery, the corresponding optimal viewpoint is automatically retrieved and applied, eliminating the need for real-time manual viewpoint adjustment and providing immediate clear visualization of the cut section from the best angle
Solution Approach 2:
The system automatically determines and switches to the optimal viewpoint when a cut section is selected, without requiring manual intervention. The viewpoint information is self-updated based on the selected cut section, allowing the system to serve itself in providing the correct viewing angle for clear visualization
2Adaptability or versatility
If manual adjustment of viewpoints is required to visualize critical areas, then flexibility in viewing angles is improved, but the time and complexity of operation increase
Solution Approach 1:
Optimal viewpoints for all possible cut sections are pre-calculated and stored in the system before surgery begins. This preliminary preparation allows instant retrieval and application of the correct viewpoint when needed, maintaining full adaptability to any cut section while eliminating time-consuming manual adjustment during surgical procedures
Solution Approach 2:
The system dynamically switches between different optimal viewpoints based on the selected cut section. Each cut section has its own pre-determined optimal viewpoint, and the system automatically transitions to the appropriate viewpoint, providing adaptable visualization without manual intervention and reducing adjustment time to nearly zero

AI summary
An image processing device includes a processor, in which the processor is configured to receive a setting of a cut section with respect to an organ shown by a three-dimensional image, and output, as a first display image that is generated by rendering based on the three-dimensional image and shows the organ, a side viewpoint image having a side viewpoint at which the set cut section is viewed from a direction intersecting a normal line of the cut section, set as a viewpoint of the rendering.
