Endoscopic AI Polyp Detection with Tool-Aware Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoscopic procedures for detecting potential malignancies, such as polyps, often rely on human visual inspection, which can be inefficient and may miss polyps that are difficult to see, leading to suboptimal detection rates.
Innovation Solution
A data processing system that utilizes an artificial neural network to analyze real-time image data from an endoscopic imaging device, processing images to identify potential malignancies and overlaying graphical indicators on the display to highlight these locations, while also detecting surgical tools to prevent overlay obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time image processing is implemented to detect polyps, then detection accuracy is improved, but processing time and computational complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-processing images to enhance contrast and highlight potential polyp regions before final analysis. The neural network is pre-trained on extensive datasets to recognize polyp patterns, enabling rapid inference during real-time endoscopic procedures without requiring complex computations at the point of detection.
Solution Approach 2:
An intermediary processing layer is introduced between the endoscopic camera and the analyst. This layer includes image enhancement algorithms and a neural network classifier that acts as a mediator to automatically identify and flag potential polyps, reducing the cognitive load and time required for manual inspection while maintaining high detection accuracy.
2Measurement precision
If graphical overlays are added to highlight potential malignancies, then detection capability is improved, but visual obstruction from overlays may occur
Solution Approach 1:
The system applies local quality by placing graphical overlays only at specific locations where polyps are detected, rather than uniformly across the entire image. The overlay characteristics (such as color, size, and shape) are locally adapted to match the surrounding tissue appearance, making the highlighted regions stand out while minimizing visual disruption to the overall field of view during endoscopic procedures.
3Measurement precision
If multiple image processing operations are performed to enhance detection, then detection accuracy is improved, but system complexity increases
Solution Approach 1:
The image processing system is segmented into distinct functional modules: image acquisition, contrast enhancement, neural network classification, and graphical overlay generation. Each module performs a specific function and can be independently optimized or replaced. This modular architecture reduces overall system complexity by allowing selective implementation of processing steps based on the specific clinical scenario and available computational resources.
Data Source
AI summary
One or more machine learning techniques can be used to identify locations of potential malignancies within images (e.g., video images) captured during a medical procedure, such as an endoscopic procedure. The images can be displayed, in real-time, on a display unit. The images can be displayed with a graphical overlay that isolates the identified locations of potential malignancies.
