Abstract: A method for reconstructing a dielectric image using electromagnetic waves, comprising: acquiring a measurement value of the electromagnetic waves; generating a matching system matrixes between the meshes; generating a smoothed dyadic Green's function matrix; generating an electromagnetic wave calculation value; calculating a misfit error between the acquired electromagnetic wave measurement value and the generated electromagnetic wave calculation value, and checking whether a change of the calculated misfit error satisfies a predetermined optimization determination condition; updating dielectric parameters at the meshes; and outputting a reconstructed dielectric image in the image reconstruction region.

Abstract: Provided is a device for microwave hyperthermia that may attach a flexible patch on the skin of a user based on a cross-section of a body tissue of the user, for example, a joint and muscle of a leg and an arm and may emit microwaves towards a plurality of points of the body tissue through the patch. The microwaves emitted toward the body tissue may have the same phase and maximum power. Accordingly, a maximum heat generation point may be generated in an area adjacent to the plurality of points. The device for microwave hyperthermia may move the maximum heat generation point by sequentially changing a phase and a direction of each of the microwaves. The device for microwave hyperthermia may uniformly distribute and maintain heat for treating pain and/or infection over the entire cross-section or a partial area. The device for microwave hyperthermia may be portable.

Abstract: A phase measurement method in a microwave tomography system may include transmitting a first Tx frequency signal, receiving a signal corresponding to the first Tx frequency signal, and measuring a first phase value; transmitting a second Tx frequency signal separated by a predetermined discrete frequency from the first Tx frequency signal, receiving a signal corresponding to the second Tx frequency signal, and measuring a second phase value; calculating a first phase difference based on a difference between the first and second phase values; calculating a second phase difference based on the discrete frequency; and determining an unwrapped phase value through comparison between the first and second phase differences.

Abstract: Disclosed are a deep body spread microwave hyperthermia device for personal uses and an operation method thereof. The operating method may include generating a control signal to control patches attached to the skin of a user, dividing the control signal into a first signal and a second signal having a phase different from a phase of the first signal, transmitting the first signal and the second signal to patches attached to different positions, among the patches, and producing hyperthermia in a body of the user by radiating radio waves based on the first signal or the second signal received by each of the patches.
