Solution Overview

Problem

Current CT image processing techniques fail to accurately highlight and display target regions in CT images, leading to incomplete information and misjudgments, especially in complex images like those from abdominal scans, due to blurring tissue boundaries and overlapping tissue densities.

Innovation Solution

A CT image processing method and apparatus that separates target regions by judging CT values of voxel points, removes false positives, and performs volume rendering to enhance border points, allowing for accurate three-dimensional display and measurement of characteristic data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If CT images are processed using traditional image processing techniques, then the processing speed is maintained, but the target regions cannot be highlighted accurately and the detection precision deteriorates

Engineering Contradiction:
Improvetarget region detection accuracyVSAvoidprocessing speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent changes the parameter of region separation from traditional intensity-based segmentation to CT value-based segmentation. By using the specific parameter of CT values (Hounsfield units) to identify target regions, the system achieves accurate detection of pathological areas while maintaining processing efficiency through automated threshold-based classification.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces an intermediary computational layer that automatically identifies and separates target regions based on CT value analysis. This intermediary processing step acts as a mediator between raw CT images and final diagnostic display, accurately highlighting target regions without requiring manual intervention or sacrificing processing speed.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If CT images display all tissue regions, then comprehensive information is provided, but the target regions are not highlighted and information completeness deteriorates

Engineering Contradiction:
Improvepathological information completenessVSAvoidimage processing complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent extracts target regions from the complex CT images by automatically identifying and separating areas with abnormal CT values. This extraction process isolates pathological information from the background tissue, ensuring complete pathological information is captured and highlighted without requiring complex manual processing.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the CT image into different regions based on CT value thresholds, separating target regions (pathological areas) from normal tissue. This segmentation approach ensures that all relevant pathological information is captured and displayed prominently, reducing information loss while maintaining manageable processing complexity through automated methods.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If doctors manually analyze CT images, then detailed observation is possible, but the detection time increases and accuracy deteriorates due to human error

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements a self-service automated system that performs target region identification and separation without requiring manual doctor intervention. The system automatically analyzes CT values, identifies pathological regions, and highlights target areas, eliminating human error while maintaining rapid detection speeds and improving overall diagnostic accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical process of manual image analysis with an automated computational system. By substituting human visual inspection with algorithm-based CT value analysis, the system achieves consistent high accuracy without detection time delays or human error, while preserving all necessary pathological information.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
