IHC Image Analysis Using Control Slides to Exclude Artifacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the analysis of biological specimens, tissue artifacts on IHC images can be misidentified by image analysis algorithms, leading to inaccurate cell counts and other incorrect results.
Innovation Solution
The use of previously unutilized control slides to identify artifact regions in IHC images, which are then excluded from analysis, thereby improving the accuracy of image analysis algorithms.

Engineering Contradiction Analysis
1Productivity
If image analysis algorithms are applied to IHC images, then automated cell counting and analysis efficiency are improved, but artifacts are misidentified as positive stains leading to inaccurate results
Solution Approach 1:
Control slides serve as an intermediary reference to distinguish artifacts from true positive stains. The algorithm compares test slide features against control slide patterns, using the control as a mediator to identify and exclude artifact regions, thereby maintaining both automation efficiency and measurement accuracy
Solution Approach 2:
The system uses control slides to provide feedback information about artifact patterns. By analyzing control slides and feeding this information back into the analysis algorithm, the system learns to recognize and exclude artifact regions, improving accuracy while maintaining automated processing
2Measurement precision
If control slides are integrated into the analysis workflow, then artifact identification and exclusion accuracy are improved, but system complexity and processing time increase
Solution Approach 1:
Control slides are processed beforehand to pre-identify artifact patterns and regions. This preliminary action creates a reference map of artifacts that can be quickly applied to test slides, reducing the complexity of real-time artifact detection while maintaining high accuracy
Solution Approach 2:
The system creates a copy or map of artifact regions from control slides and applies this information to test slides. By copying the artifact pattern information rather than re-analyzing raw images, the system reduces processing complexity while maintaining accurate artifact identification

AI summary
Systems and methods for automatically excluding artifacts from an analysis of a biological specimen image are disclosed. An exemplary method includes obtaining an immunohistochemistry (IHC) image and a control image, determining whether the control image includes one or more artifacts, upon a determination that the control image includes one or more artifacts, identifying one or more artifact regions within the IHC image by mapping the one or more artifacts from the control image to the IHC image, and performing image analysis of the IHC image where any identified artifact regions are excluded from the image analysis.
