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.
