Other AbstractThe invention relates to novel medical signal treatment, acquisition and analysis techniques, in particular to an acquisition and analysis system for non-contact detection and treatment of magnetogastric signals on the basis of a giant magneto-impedance sensor. The system comprises a magnetogastric signal acquisition module, a data conversion processing module and a display terminal, the magnetogastric signal acquisition module is used for acquiring and amplifying magnetogastric signals, the data conversion processing module is connected with the magnetogastric signal acquisition module and used for converting the magnetogastric signals from the magnetogastric signal acquisition module, from analog signals into digital signals, and performing calculating to initial diagnostic parameters, and the display terminal is connected with the data conversion processing module and used for displaying parameters obtained by calculating of the data conversion processing module. The use of the giant magneto-impedance sensor ensures complex magnetogastric signals are sensed efficiently. By using a filter amplification module, the influence of clutter signals is minimized, and minute magnetogastric signals of 3CPM band are extracted.
