Smear Staining Quality Control Using Regional Image Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quality control methods for smear preparations do not account for variations in smearing/staining conditions across different laboratories or regions, leading to inconsistent staining states in smear samples.
Innovation Solution
A method and apparatus that generate smear quality control information by obtaining feature values from multiple image data sets, reflecting staining states, and generating quality control information adapted to specific laboratory or regional conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If predetermined reference values are used for quality control, then quality control can be performed, but the control is not adapted to variations in smearing/staining conditions across different laboratories or regions
Solution Approach 1:
The patent changes the reference parameter from fixed predetermined values to dynamically generated reference values based on actual image data from the specific laboratory or region. The generating apparatus collects image data from multiple smears, extracts feature values reflecting staining states, and generates reference values that adapt to local conditions while maintaining evaluation precision through statistical processing of multiple samples.
2Reliability
If quality control is performed without considering regional variations, then the process is simple, but the quality control information is not accurate for different laboratories or regions
Solution Approach 1:
The patent applies preliminary action by pre-collecting and processing image data from multiple smears to generate reference values before actual quality control evaluation. The generating apparatus performs preliminary statistical analysis on feature values extracted from multiple image data sets, creating a baseline that simplifies subsequent quality control operations while ensuring reliability through pre-established regional adaptations.
3Adaptability or versatility
If multiple image data are processed to generate quality control information, then adaptability to regional conditions is improved, but the processing time and complexity increase
Solution Approach 1:
The patent uses copying by extracting feature values from multiple image data sets to create a statistical representation of regional staining conditions. Instead of processing complete images repeatedly, the system copies and analyzes key feature values (color components, luminance values) from multiple smears, generating reference values that capture regional characteristics while reducing processing time through feature-based analysis.
