Multi-input and Multi-variable systems

482
Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.
In the absence of...

Model-Independent Approaches for Pharmacokinetic Data: Noncompartmental Analysis

396
Noncompartmental analyses offer an alternative method for describing drug pharmacokinetics without relying on a specific compartmental model. In this approach, the drug's pharmacokinetics are assumed to be linear, with the terminal phase log-linear. This assumption allows for simplified analysis and interpretation of the drug's behavior in the body.
One important characteristic of noncompartmental analyses is that drug exposure increases proportionally with increasing doses. This...

Mass Spectrometry: Complex Analysis

2.1K
Mass spectrometry is an important technique for the identification of pure compounds. However, it has some limitations for the analysis of complex mixtures, often due to excessive fragmentation making the spectrum too complicated to decipher. Mass spectrometry can be combined with suitable separation methods in sequence, forming hyphenated methods, which are useful in the analysis of complex mixtures.
GC–MS is a powerful hyphenated method commonly used in forensics and environmental...

Model Approaches for Pharmacokinetic Data: Distributed Parameter Models

311
Pharmacokinetic models are mathematical constructs that represent and predict the time course of drug concentrations in the body, providing meaningful pharmacokinetic parameters. These models are categorized into compartment, physiological, and distributed parameter models.
The distributed parameter models are specifically designed to account for variations and differences in some drug classes. This model is particularly useful for assessing regional concentrations of anticancer or...

Area of Science:

  • Medical Informatics
  • Radiology
  • Data Science

Background:

  • Retrospective data mining is crucial for research but is often time-consuming and labor-intensive.
  • Existing data mining software struggles with complex patient criteria and variations in radiology report language.
  • Identifying patients with specific radiologic findings across multiple imaging modalities presents a significant challenge.

Purpose of the Study:

  • To present an algorithmic approach to enhance retrospective data mining for complex patient cohort identification.
  • To address the limitations of keyword and Boolean searches in identifying patients with multiple, specific criteria.
  • To improve the efficiency and accuracy of data mining in Picture Archiving and Communication Systems (PACS) databases.

Main Methods:

  • Development of a novel algorithmic approach for data mining.
  • Application of the algorithm to a real-world dataset within an institutional PACS database.
  • Focus on identifying patients matching several independent and complex variables.

Main Results:

  • The proposed algorithm successfully identified patients meeting multiple, complex search criteria.
  • Demonstrated the algorithm's effectiveness in a practical, real-world data mining scenario.
  • Overcame challenges associated with variations in radiology report descriptions.

Conclusions:

  • The developed algorithmic approach offers a powerful solution for complex retrospective data mining.
  • This technique significantly improves the ability to identify specific patient cohorts for research.
  • The method has practical implications for enhancing medical research using PACS data.
