Biomedical Signal and Image Processing

A Biosignal is any signal in living beings which will be continually measured and monitored. The term biosignal is usually used to refer to bioelectrical signals, but it's going to refer to both electrical and non-electrical signals. The standard understanding is to refer only to time-varying signals, although spatial parameter variations (e.g. the nucleotide sequence determining the genetic code) are sometimes subsumed also. An electrical bio signal, or bioelectrical time signals, usually refers to the change in current produced by the sum of an electrical potential difference across a specialized tissue, organ or cell system just like the nervous system. Thus, among the best-known bioelectrical signals are:

•  Electroencephalogram (EEG)
•  Electrocardiogram (ECG)
•  Electromyogram (EMG)
•  Electrooculogram (EOG)
•  Electroretinogram (ERG)
•  Electrogastrogram (EGG)
•  Galvanic skin response (GSR) or electro dermal activity (EDA)

Medical imaging is that the technique and process of imaging the interior of a body for clinical analysis and medical intervention, also as visual representation of the function of some organs or tissues (physiology). Medical imaging seeks to reveal internal structures hidden by the skin and bones, also as to diagnose and treat disease. Medical imaging also establishes a database of normal anatomy and physiology to form it possible to identify abnormalities.
