ECG Signal Image Standardization via Background Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for determining the image quality of electrocardiogram (ECG) signals are inadequate, leading to altered or skewed determinations due to various camera and environmental factors.
Innovation Solution
An apparatus and method for standardizing ECG signal images, which includes an imaging device, a processor, and a memory. The system receives an overlay image, identifies a captured fixed background image and a primary ECG image, compares the fixed background image to quality thresholds, determines an image quality score, and outputs image modification data based on this score.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current image quality determination systems are used for ECG signals, then the assessment process is simple, but the measurement precision is poor due to camera and environmental factors altering the results
Solution Approach 1:
The patent segments the image quality assessment into multiple independent components: camera parameter analysis, environmental factor evaluation, and ECG signal quality metrics. Each component is assessed separately and then integrated to produce an overall quality score, improving measurement precision while managing system complexity through modular design
Solution Approach 2:
The patent introduces intermediary control elements including standardized lighting conditions, fixed camera parameters, and reference ECG templates. These intermediaries mediate between the variable environmental factors and the quality assessment, ensuring consistent and accurate measurements across different conditions
2Measurement precision
If standardized image quality assessment is implemented, then measurement precision improves, but the ease of operation decreases due to multiple parameters and thresholds to manage
Solution Approach 1:
The system performs self-service by automatically capturing camera parameters, environmental conditions, and ECG signal characteristics. The processor autonomously compares these parameters against predefined thresholds and generates quality scores without requiring manual intervention, maintaining measurement precision while preserving ease of operation
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously monitors image quality parameters and provides real-time quality scores. When quality thresholds are not met, the system provides feedback on specific parameters that need adjustment, guiding operators to make precise corrections without overwhelming them with complex manual assessment procedures
