Problems solved by technology

[0005] In order to obtain a clearer EEG signal, the cardiac shock artifact signal can be extracted first and then suppressed, but the traditional cardiac shock artifact signal extraction device usually uses a computer to extract and display the cardiac shock artifact signal, which is large in size and not easy to carry

Abstract

The invention discloses a heart impact artifact signal extraction device and method, and belongs to the technical field of biomedicine signal processing. The method includes the steps that electrocardiosignals and electroencephalogram signals synchronously collected by EEG-fMRI are transmitted to a heart impact artifact signal extraction module; the heart impact artifact signal extraction module processes the electroencephalogram signals with a fast ICA blind signal processing algorithm based on negentropy and a heart impact artifact signal extraction method with the electrocardiosignals as reference signals, and heart impact artifact signals are obtained through extraction; a signal display module is used for displaying the heart impact artifact signals in real time. The heart impact artifact signal extraction device has the advantages that a lead system is simple in design and convenient to obtain, and the heart impact artifact signal extraction device is capable of extracting the heart impact artifact signals in real time, facilitates clinical application, and is small in size and convenient to carry.

Description

technical field [0001] The invention relates to the technical field of biomedical signal processing, in particular to a cardiac shock artifact signal extraction device and a corresponding cardiac shock artifact signal extraction method. Background technique [0002] With the obvious rising trend of various brain diseases such as epilepsy, Alzheimer's disease, Parkinson's syndrome, etc., people's understanding of brain function is constantly deepened. The brain is rich in information, complex in structure, and powerful in function. It is the highest component of the central nervous system of the human body and controls people's thinking, language, and actions. Only with an in-depth understanding of these information can useful signals be extracted to solve current brain medical pathological problems. [0003] MantiniD in 2007 concluded that EEG signals recorded in MRI scanners are often contaminated by cardiac shock artifact signals. The cardiac shock artifact signal comes ...
