Panoramic Peripheral Image Generation for Virtual Colonoscopy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual colonoscopy technologies face challenges in accuracy due to the large number of images medical professionals must examine and the presentation of images, which can obscure features of interest within the colon, leading to potential missed detections of polyps or tumors.
Innovation Solution
The creation of a panoramic peripheral image that allows medical professionals to view anterior and posterior images simultaneously with additional orthogonal views, enabling a seamless and efficient examination of the virtual colon model by stitching multiple peripheral images together to reduce seams and deformations, and using spherical shells to generate a 360° view that minimizes distortions and enhances feature visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional anterior and posterior views are used to examine the colon, then the examination can be performed with simple imaging, but features of interest may be obscured and detection accuracy decreases
Solution Approach 1:
The patent transitions from traditional 2D anterior and posterior views to a panoramic peripheral view that encompasses multiple dimensions of the colon interior. This panoramic view provides a comprehensive 360-degree perspective, allowing medical professionals to observe features of interest from multiple angles simultaneously, thereby improving detection accuracy without requiring complex multi-device imaging systems
Solution Approach 2:
The patent merges multiple peripheral images into a single seamless panoramic view. By stitching together images from different angles and positions, the system creates a unified comprehensive view that consolidates information that would otherwise require examining multiple separate images, thus improving detection accuracy while maintaining relatively simple imaging technology
2Productivity
If multiple separate images are examined to detect abnormalities, then comprehensive coverage can be achieved, but the time and effort required for examination increases
Solution Approach 1:
The patent combines multiple peripheral images into a single panoramic peripheral view that displays comprehensive colon coverage in one continuous image. This allows medical professionals to examine the entire colon interior without manually reviewing multiple separate images, significantly reducing examination time and effort while maintaining comprehensive diagnostic coverage
Solution Approach 2:
The panoramic view is generated by stitching together multiple peripheral images that capture different sections of the colon. This segmentation approach allows the system to cover the entire colon comprehensively while presenting the information in a unified seamless format that improves examination efficiency
3Stability of the object's composition
If peripheral images are stitched together to create panoramic views, then seamless viewing is achieved, but seams and deformations may occur at image boundaries
Solution Approach 1:
The patent applies preprocessing techniques to peripheral images before stitching them into the panoramic view. This preliminary action includes geometric corrections, distortion compensations, and alignment adjustments that prevent seams and deformations from occurring at image boundaries, ensuring a seamless continuous panoramic display

AI summary
A method of creating a panoramic peripheral image may include identifying a virtual observer at a position in a modeled scene. Peripheral images of the modeled scene may be obtained, including views at multiple angles from the virtual observer. The peripheral images may be arranged to depict a panoramic peripheral view of the modeled scene.
