Solution Overview

Problem

Current algorithms for analyzing histochemical or cytological samples with complex staining patterns are inadequate as they often miss nuclei or fail to detect membrane staining outside predefined neighborhoods, leading to incomplete or incorrect quantification, especially when multiple staining compartments are intermixed.

Innovation Solution

An improved image analysis system that segments digital images into distinct regions based on analyte staining patterns, generates analyte intensity maps, and identifies analytically relevant portions within compound staining regions to quantify analyte staining accurately, even in regions with intermixed staining patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If algorithms use predefined neighborhood radius around nuclei to detect membrane staining, then detection process is simplified, but staining outside the predefined neighborhood is missed

Engineering Contradiction:
Improvedetection process simplicityVSAvoidmembrane staining detection completeness
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The algorithm dynamically adjusts the neighborhood radius for each nucleus based on the actual distance to the membrane, rather than using a fixed predefined radius. This allows the detection region to adapt to varying cell sizes and membrane positions, ensuring complete membrane staining detection while maintaining computational efficiency.

2Device complexity

If algorithms focus on single compartment staining detection, then analysis is simpler, but intermixed staining patterns are ignored

Engineering Contradiction:
Improveanalysis complexityVSAvoidstaining quantification accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The algorithm segments the staining pattern into distinct biological compartments (membrane, cytoplasm, nucleus) and analyzes each compartment separately. By identifying characteristic staining patterns for each compartment and processing them independently, the system achieves accurate quantification of intermixed staining patterns without excessive computational complexity.

Inventive Principle:
Principle #1Segmentation

3Productivity

If algorithms use fixed detection regions around nuclei, then processing speed is maintained, but staining in variable locations is missed

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The detection region is dynamically defined based on the actual spatial relationship between nuclei and membrane staining, rather than using fixed geometric shapes. The algorithm identifies membrane staining at variable distances from nuclei by adapting the search region to each cell's morphology, ensuring complete detection while maintaining processing efficiency through optimized search strategies.

Inventive Principle:
Principle #15Dynamics
