Abstract

The invention provides a magnetocardiogram data set processing method, a system, a device and a computer readable storage medium. The magnetocardiogram data set processing method comprises the steps that a multi-cycle magnetocardiogram data set is obtained; preprocessing is carried out on the magnetocardiogram data set, so that imaging is carried out the magnetocardiogram data set, and current density distribution data are obtained; the current density distribution data is a two-dimensional current density vector, distributed on a measurement plane, of three-dimensional current density; projecting is carried out on the current density distribution data in an electrocardio lead direction to obtain lead direction projection components of the two-dimensional current density vector at all moments of a single cycle; and the lead direction projection components, at all moments of the single cycle, of the two-dimensional current density vector have corresponding relations with a lead electrocardiogram data curve. According to the magnetocardiogram data set processing method, the system, the device and the computer readable storage medium, the problem of how to compare the electrocardiogram with the magnetocardiogram can be solved, and the problem of electrical activity of a heart can be reflected more accurately.

Description

technical field [0001] The invention belongs to the technical field of magnetocardiography, and relates to a processing method and system, in particular to a processing method, system, equipment and computer-readable storage medium of a magnetocardiogram data set. Background technique [0002] Electrocardiography (ECG) is a technology that uses an electrocardiograph to record the electrical activity changes generated by the heart every cardiac cycle from the body surface. Electrocardiogram leads have contact skin resistance interference, and are also affected by bones, body fluids and skin. The ECG waves projected by magnetocardiography can more accurately reflect the electrical activity of the heart. However, the prior art cannot provide a comparison between the magnetocardiogram and the electrocardiogram, resulting in problems such as inaccurate feedback of the electrical activity of the heart. [0003] Therefore, the present invention provides a processing method, syste...
