BioSigPlot: an opensource tool for the visualization of multi-channel biomedical signals with Matlab

Area of Science:

• Biomedical Engineering
• Neuroscience
• Medical Informatics

Background:

• Effective visualization and analysis of multi-channel biomedical signals, particularly electroencephalography (EEG), are crucial for interdisciplinary research involving engineers and clinicians.
• Existing software tools may lack the flexibility or specific features required for advanced signal processing experimentation and collaborative analysis.

Purpose of the Study:

• To introduce BioSigPlot, a novel Matlab-based software designed for the visualization and analysis of multi-channel biomedical signals.
• To provide a highly customizable and user-friendly interface for signal processing experimentation, catering to both engineering and medical researchers.
• To highlight the unique advantages of BioSigPlot, including multi-dataset display, video synchronization, and online processing capabilities.

Main Methods:

• Development of BioSigPlot using Matlab (MathWorks Inc.) with an object-oriented programming approach.
• Implementation of a customizable graphical user interface (GUI) controllable via both graphic controls and command lines.
• Integration of common physician tools and features for signal processing experimentation.

Main Results:

• BioSigPlot enables the visualization of multi-channel biomedical signals, with a focus on EEG data.
• The software supports multi-dataset displaying, synchronization with video, and online processing, offering advantages over existing tools.
• The object-oriented design allows for flexible control through both GUI and command-line interfaces.

Conclusions:

• BioSigPlot serves as a valuable, free, and open-source tool for researchers requiring advanced visualization and analysis of biomedical signals.
• Its customizable nature and advanced features facilitate collaborative research between engineering and medical disciplines.
• The software is distributed under the GNU Public License, promoting open-source development and non-commercial use.
