Embodiment Construction

[0051] The electrical properties of biological tissue are closely related to the health of the physiological system. When diseases such as breast cancer and leukemia occur, the dielectric properties of biological tissue (commonly expressed by the dielectric constant) change significantly. The dielectric properties of different types of biological tissues are significantly different. The dielectric constant of biological tissues with high water content such as bones and tumors is higher than that of biological tissues with low water content such as fat. The physiological and pathological state of the body provides a feasible physical basis. Magnetic induction bioimaging reconstructs the image by measuring the electromagnetic field distribution inside and around the target organism under the action of the excitation magnetic field, and obtains important characteristics such as the dielectric constant distribution, electrical conductivity distribution, temperature distribution and...

Abstract

The invention relates to a non-contact type magnetic induction imaging system and an imaging method thereof. The imaging system comprises a signal generating module, a signal transmitting module, a control module, a signal receiving module, a signal processing module and an image display module. The control module controls the signal generating module to generate a single-frequency radio frequency signal, the radio frequency signal is applied into the signal transmitting module in an alternating current mode, an alternating magnetic field is generated through the alternating current, the signal receiving module receives the alternating magnetic field and transmits the received signal to the signal processing module through the control module, the signal processing module reconstructs the received signal to obtain a two-dimensional restructured image of a target living body, and the two-dimensional restructured image is transmitted to the image display module to be displayed. The imaging method comprises the steps of electromagnetic wave stimulation, echo signal measuring, target living body two-dimensional imaging processing and two-dimensional restructured image display.

Description

technical field [0001] The invention belongs to the technical field of magnetic induction imaging, and in particular relates to a non-contact magnetic induction imaging system and an imaging method thereof. Background technique [0002] Currently, X-CT, MRI and other imaging methods can be used to image brain edema caused by cerebral hemorrhage and ischemia, but X-CT is not easy to be used repeatedly due to the presence of radioactivity, and both X-CT and MRI are large-scale equipment, which cannot Continuous use at the bedside cannot monitor the development of cerebral edema continuously and in real time. The non-contact magnetic induction imaging method is a method for monitoring changes in electrical conductivity distribution in biological parts such as the brain, which can be used for the detection of brain diseases. Non-contact, non-invasive testing methods are new in the medical field. The magnetic induction imaging method for mapping organisms with arbitrary shapes ...
