Abstract

The invention provides a full-tensor magnetocardiography probe and a producing method thereof. The full-tensor magnetocardiography probe comprises a full-tensor probe support, a detection layer SQUID (superconducting quantum interference device) magnetometer and a reference layer SQUID magnetometer, wherein the full-tensor probe support comprises a detection layer support, a reference layer support and middle connecting rods, the detection layer support is arranged at bottom ends of the middle connecting rods, and the reference layer support is arranged at top ends of the middle connecting rods; the detection layer SQUID magnetometer comprises a plurality of SQUID magnetometers which are arranged on the detection layer support and used for synthesizing five independent first-order gradients and required uniform components; the reference layer SQUID magnetometer comprises three SQUID magnetometers which are arranged in three orthogonal directions of the reference layer support to form a three-axis magnetometer. With the adoption of the full-tensor magnetocardiography probe and the producing method thereof, the five independent first-order gradients and the 2-3 uniform components of a magnetic field can be acquired, and noises of the five independent first-order gradients are effectively inhibited, so that more magnetic field and electrical activity information of magnetocardiograms is acquired.

Description

technical field [0001] The invention relates to a probe and a manufacturing method thereof, in particular to a full tensor magnetocardiograph probe and a manufacturing method thereof. Background technique [0002] There is a wealth of electromagnetic information hidden behind the life activities of the human body. Magnetocardiography is a new method for diagnosis of heart diseases by detecting the spatial magnetic field generated by the electrical activity of the human heart and performing imaging analysis. Similar to the traditional electrocardiogram, magnetocardiography reflects the electrophysiological activity of the heart and is a functional imaging method. Because it is completely non-invasive, non-radiative, non-contact, less affected by body fluids and bones, and can respond to annular eddy currents, the magnetocardiogram contains many electrophysiological information that cannot be reflected in the traditional electrocardiogram, thus showing better sensitivity and...
