Multimodal biological signal synchronization detection system and method

Abstract

The invention provides a system for synchronously detecting multi-modal biological signals. The system comprises a signal collecting module and a signal processing module, wherein the signal collecting module is used for synchronously collecting multi-source signals in real time, and the signal processing module is connected with the signal collecting module and used for fusing and analyzing the multi-source signals. The signal collecting module comprises an ultrasonic image collecting unit for collecting ultrasonic images, a physiological signal collecting unit for collecting physiology signals and a kinematics signal collecting unit for collecting kinematics signals. The signal processing module is used for controlling the signal collecting module to synchronously collect the ultrasonic images, the physiological signals and the kinematics signals in real time through a multithreading communication method and a timestamp method. The signal processing module processes the signals through a feature extraction and statistical learning method and establishes a motion model. According to the system, the advantages that the ultrasonic imaging technology is noninvasive, convenient to apply and cheap in application are utilized, the comprehensive ultrasonic imaging technology and the motion and electric physiology technologies are integrated, and human motion multi-information can be synchronously detected in real time. The invention further provides a method for synchronously detecting the multi-modal biological signals.

Problems solved by technology

[0008] In the existing technology, for the acquisition of various information on human body movement, most of them still use multiple detection devices to operate separately. When each device operates independently, it is difficult to maintain and lack compatibility, and it is difficult to integrate information into one Comprehensive processing and analysis under a unified system framework

Although it has been reported that the high-speed imaging system is integrated into the measurement of human motion information, it can only reflect the external characteristics of human motion behavior, and cannot deeply and accurately reflect the internal structure and morphological changes of human motion muscles.

However, using other imaging techniques, such as nuclear magnetic resonance (MRI), to study muscle changes requires the face of practical problems such as expensive MRI equipment and complicated operations.
