Method, system, medium and device for synchronizing multiple scanning data of magnetocardiography

Abstract

The invention provides a method, a system, a medium and a device for synchronizing multiple scanning data of a magnetocardiography, and the method comprises the steps: acquiring n times of magnetocardiogram data based on a plurality of detection channels, obtaining magnetocardiogram data from a first region to an nth region, and obtaining magnetocardiogram data of an (n+1)th region; respectively selecting the magnetocardiogram data of one detection channel included by the magnetocardiogram data of the (n+1)th region from the magnetocardiogram data of the first region to the nth region, and obtaining common point magnetocardiogram data of the first region to the nth region; identifying R peaks of the common dessert magnetic data from the first region to the nth region, and obtaining the R peaks of the common dessert magnetic data from the first region to the nth region; selecting any one of R peaks of the common point magnetic data of the first region and the nth region as a reference R peak, and calculating the time relation between other R peaks and the reference R peak; performing translation based on the moment relation, and obtaining synchronous multi-channel magnetocardiogram data. The method is used for obtaining the synchronous multi-channel magnetocardiogram data based on the single magnetocardiogram instrument.

Description

technical field [0001] The invention relates to the technical field of magnetocardiographs, in particular to a method, system, medium and device for synchronizing multiple scan data of magnetocardiographs. Background technique [0002] Magnetocardiograph is a new type of heart disease monitoring equipment that detects the magnetic field of the human heart for imaging analysis. It has the advantages of being completely non-invasive, non-contact, non-radiation, and high sensitivity. It has shown good application potential in ischemic heart disease . [0003] In the measurement of the magnetic field signal, the magnetic field signal covering a certain area of ​​the human thoracic plane is usually obtained by multi-point scanning or one-time detection, and the imaging analysis is carried out. Taking the standard 36-channel array as an example, 4 detection channels can be used for 9 scans, or 9 detection channels can be used for 4 scans, or 36 detection channels can be used for ...
