Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto. It should be pointed out that, if there are any processes or parameters that are not specifically described in detail below, those skilled in the art can refer to the prior art.

[0042] This embodiment mainly proposes a magnetopulmonography inspection method and device according to the requirements of magnetopulmonography detection.

[0043] The detection principle of the present invention is as figure 1 shown. A pair of narrow and thin strip-shaped transmitting coils 102 are arranged before and after the human lungs 101, the front of which is as figure 2 As shown, and the magnetic noise interference is removed by the active magnetic shield 103 . The broadband detection signal generated by the data processing module is transmitted to the transmitting unit of the target de...

Abstract

The invention provides a detection method and device for magnetopneumogram. The detection device comprises a detection terminal composed of broadband push-pull type transmitting coil pairs and high-sensitivity receiving arrays, a target detection module, a data processing module, an active magnetic shielding module and a cloud computing module, wherein the detection terminal is connected with the target detection module, the target detection module and the active magnetic shielding module are connected with the data processing module, and the data processing module is connected with the cloud computing module. According to the detection method, an active shielding case offsets external magnetic noise at a detection point, current inside transmitting coils is controlled through broadband alternating signals, and alternating magnetic fields are actively applied in front of and behind the chest of a human body through coils. According to the electromagnetic induction principle, the alternating magnetic fields actively transmitted by the power-on coils generate an induced magnetic field in metal dust, a distribution diagram of a lung magnetic field is obtained through array signal receiving and multi-target magnetic field inversion and splicing, and rapid, efficient and high-precision magnetopneumogram detection is achieved.

Description

technical field [0001] The invention relates to the technical field of detection of pneumoconiosis, in particular to a detection method and device of a magnetic lung map. Background technique [0002] Magnetopulmonography refers to the distribution map of the lung magnetic field at various points in the chest. Existing measurement methods mainly use the ferromagnetic properties of lung dust, magnetize it with a medium-strength magnetic field outside the body, and measure the residual magnetic field of the dust on the body surface after removing the magnetic field. Compared with the traditional X-ray and lung function detection, it has the characteristics of non-destructive and high sensitivity, and has good application value in the early diagnosis and early prevention of pneumoconiosis. However, the following problems exist in practical applications: [0003] (1) The average magnetic induction intensity of the lung magnetic field is about , relative to the geomagnetic fi...
