Biosignal processing
The biosignal is a branch of the medical computer science that deals with the analysis of bio-signals by means of methods of mathematics and computer science . When processing bio-signals, the convolution of discrete functions is of particular importance. Biomedical image processing can also be counted in the field of biosignal processing . Peter Reichertz defines bio-signal processing as the " analysis of bio and other signals and their processing for a higher aggregation of information, possibly also for direct process control ".
tasks and goals
- Support of the physician in the quantitative assessment of signals and images (diagnostic support)
- Automatic classification of signals and images ( screening examinations)
- Monitoring and control of vital functions ( intensive care medicine )
- Formal description of relationships and dependencies of physiological functions (medical research)
- Control and regulation of physiological functions using prostheses and devices (prosthetics, organ replacement, stimulation)
Applications
Biosignal processing is used u. a.
- in cardiology ( electrocardiography [EKG], intracardiac pressure curves, phonocardiography)
- in neurology ( electroencephalography [EEG], evoked potentials)
- for pulmonary diseases (lung function tests)
- for muscular or neurogenic diseases ( electromyography [EMG])
- ophthalmological diseases ( electroretinography [ERG])
