The invention relates to a three-dimensional imaging method based on a wearable
magnetocardiography three-dimensional measuring device, and the wearable
magnetocardiography three-dimensional measuring device obtains all three-dimensional
magnetocardiography signals of a
human body through a plurality of measuring sensors fixed by an adjustable
vest in a magnetic shielding space. The method comprises the following steps: screening transmitted three-dimensional magnetocardiogram signals according to preset amplitude information, carrying out
noise reduction and dimension reduction
processing on the screened magnetocardiogram signals by adopting an
independent component analysis and empirical mode
decomposition method, and establishing a three-dimensional grid model comprising a
trunk region, a heart region and a double-
lung region based on a CT (
Computed Tomography) image of a
human body, a
lead field matrix of
magnetic field conduction from the heart to the position of the in-vitro sensor is obtained in a forward solving mode, and
magnetic field distribution, used for real-time display, of the outer
membrane surface of the heart is reversely solved based on the
lead field matrix and the multi-channel signals. The wearable magnetocardiogram three-dimensional measuring device can synchronously obtain the three-dimensional magnetocardiogram signals, analyzes and displays the three-dimensional magnetocardiogram signals in real time, and is low in cost and convenient to carry.
