Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscopic examination systems fail to easily determine the position at which treatments, such as biopsies, are performed, particularly in large intestines, as they either lack spatial context or timing information.
Innovation Solution
An endoscopic examination support device and method that synthesizes captured image data with treatment information to generate a developed image, adding position markers for treatments, enabling easy visualization of treatment locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only endoscopic images are displayed without additional processing, then the imaging process is simple, but it is difficult to determine the position at which treatment is performed
Solution Approach 1:
The patent transforms two-dimensional endoscopic images into a three-dimensional virtual model of the luminal organ, enabling precise position determination by adding spatial depth information. This dimensional transformation allows treatment positions to be accurately identified in 3D space while maintaining relatively simple processing through automated model generation.
Solution Approach 2:
The patent creates a virtual model that copies and represents the actual luminal organ structure. This virtual copy includes position information of treatment sites, allowing accurate position determination without requiring complex analysis of the original images. The virtual model serves as a simplified representation that preserves essential spatial relationships.
2Loss of information
If treatment position information is added to the developed image, then position identification is improved, but the image processing becomes more complex
Solution Approach 1:
The patent merges multiple pieces of information (endoscopic images, treatment timing data, and spatial coordinates) into a single integrated virtual model. This consolidation preserves all treatment position information while streamlining the processing through unified model generation rather than separate analysis steps.
Solution Approach 2:
The system automatically extracts and integrates treatment position information from the endoscopic images and treatment data without requiring manual annotation or complex post-processing. The virtual model generation process itself performs the information integration, eliminating the need for separate complex synthesis steps.
3Area of stationary object
If a developed image is generated from multiple captured images, then the overview of the luminal organ is improved, but the processing time increases
Solution Approach 1:
The patent performs preliminary organization and alignment of captured images during the acquisition phase, preparing them for rapid virtual model construction. By pre-processing images to establish spatial relationships and coordinates, the subsequent virtual model generation can be performed quickly while still achieving comprehensive visual coverage of the luminal organ.
Solution Approach 2:
The patent transforms the processing approach from traditional image stitching to parameter-based virtual model construction, where key spatial parameters (coordinates, angles, distances) are extracted and used to build the 3D model. This parameter-driven approach reduces processing time compared to pixel-level image synthesis while maintaining comprehensive visual coverage.
Data Source
AI summary
An endoscopic examination support device stores, in a memory, a plurality of pieces of captured image data obtained by a plurality of imagings by an endoscope in a state in which the endoscope is inserted into a subject, and treatment information indicating treatment performed by using the endoscope in the state. Moreover, the endoscopic examination support device generates, based on the stored plurality of pieces of captured image data and treatment information, a large intestine developed image of an inside of the subject obtained by synthesizing the plurality of pieces of captured image data, the large intestine developed image being added with biopsy position mark indicating a position in the subject at which the treatment is performed, and displays the generated large intestine developed image on a display device.
