Abstract:
A radio wave sensing method for image diagnosis of breast cancer comprises a step of arranging a plurality of transceiving antennas around the breast; a step of transmitting a radio signal to at least one first antenna among the transceiving antennas; a step of receiving a scattered wave signal with respect to the radio signal from the other antennas except for the first antenna among the transceiving antennas; and a step of rotating the trasceiving antennas by a predetermined angle.
Abstract:
Provided is an image restoration system for removing the influence of scattered electromagnetic waves in an MT system. The image restoration system for removing the influence of scattered electromagnetic waves comprises a tank part which has a liquid with permittivity and conductivity similar to that of a subject, and a free space; an electromagnetic wave transceiver which includes at least one transmitting antenna emitting electromagnetic waves inside the tank part and at least one receiving antenna receiving the electromagnetic waves; an absorption part which absorbs the electromagnetic waves scattered by an object except the subject inside the tank part; and an image restoration part which restores an image using an image restoration algorithm by considering a predetermined structural boundary condition based on the electromagnetic waves detected in the electromagnetic wave transceiver.
Abstract:
PURPOSE: A three-dimensional object shape measurement device is provided to measure a three-dimensional shape of an object with a simple device and driving structure without the need of a liquid-filled tub and the interference of a radio wave transmission/reception antenna by using object shadow information generated by light inputted from the outside. CONSTITUTION: A light-transmitting part(100) is connected to one side of a panel, transmits external light, and projects the light on the internal space of the panel. A light-receiving part(110) is connected to the other side of the panel and installed at a position facing the light-transmitting part, and generates a shadow for an object located in the internal space of the panel. A rotary part(120) is connected to the panel and moves the panel by rotation. A measurement part(130) measures a three-dimensional shape of the object by using each shadow generated at the light-receiving part whenever the panel is moved by rotation. [Reference numerals] (130) Measurement part; (140) Initialization part; (150) Control part

Abstract:
PURPOSE: An apparatus and a method for reducing electromagnetic waves in a radiator are provided to reduce the surface current and diffraction waves caused by the electromagnetic waves generated from the radiator. CONSTITUTION: An electromagnetic wave reducing apparatus(100) in a radiator includes an electromagnetic wave blocking unit and an absorber(130). The electromagnetic wave blocking unit reduces the surface current due to the electromagnetic waves generated from the radiator. The absorber reduces the surface current around the electromagnetic wave blocking unit and the diffraction wave radiated from the end of the structure. The electromagnetic wave absorbing rate and the performance of the radiator is regulated by adjusting the length of the absorber.
