EEG Diagnostic System Using Digital Library for Statistical Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack an effective method for interpreting complex medical data, such as EEG signals, to aid in accurate diagnosis and prediction of ailments, as they often rely on manual analysis and limited statistical comparisons.
Innovation Solution
A system comprising a data collection station, data acquisition module, user application station, statistical databases, and a digital library that processes EEG data using statistical characterization and comparison techniques to generate indexes like trait, diagnostic, treatment, and predictive indices, enabling improved interpretation and diagnosis by comparing patient data to a base group of normal subjects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual analysis methods are used to interpret EEG data, then device complexity is reduced, but diagnostic accuracy and measurement precision deteriorate
Solution Approach 1:
The patent introduces a digital library as an intermediary component that bridges the gap between raw EEG data and diagnostic interpretations. This digital library contains pre-processed statistical data, normative values, and interpretive frameworks that automatically compare patient EEG patterns against established benchmarks, thereby enhancing diagnostic accuracy without requiring the physician to manually perform complex statistical analyses.
Solution Approach 2:
The system creates digital copies of normative EEG data and statistical characteristics from large databases of normal subjects. These copied data are stored in the digital library and automatically retrieved during patient analysis, allowing the system to perform complex statistical comparisons without manual intervention while maintaining high measurement precision through automated processing.
2Measurement precision
If automated statistical analysis is implemented, then diagnostic accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The digital library is designed to automatically retrieve, process, and present relevant statistical information and interpretive guidance without requiring the physician to manually search through extensive databases or perform complex queries. The system self-services by automatically matching patient EEG characteristics against stored normative data and presenting ready-to-interpret results, thereby maintaining ease of operation while improving diagnostic accuracy.
3Measurement precision
If comprehensive statistical databases are used, then measurement precision is improved, but device complexity and data processing requirements increase
Solution Approach 1:
The patent segments the comprehensive statistical database into organized categories within the digital library, such as normative databases, correlative databases, and predictive indices. Each segment contains pre-processed data for specific purposes (e.g., age-matched normative values, symptom-correlated patterns), allowing the system to retrieve and process only the relevant portions of data needed for each specific diagnostic question, thereby reducing processing complexity while maintaining precision.
Data Source
AI summary
The medical data analysis system automatically identifies medical information sources which correlate to anomalies identified in a set of patient medical data relating to an identified patient. The system includes a digital library for providing access to a plurality of information sources which relate to interpreting patient medical data and possible diseases associated with the patient medical data. A data characterization module calculates normative variations of a set of patient medical data to identify anomalies. Based upon this statistical analysis, a digital library interface module searches the digital library for information sources relating to the set of patient medical data and interpretations of the identified anomalies. There is also an information access module which provides an authorized user, such as a physician, with access to the information sources returned by the digital library interface module and relating to this set of patient medical data.
