Abstract:
The present invention relates to a breast phantom for microwave imaging, a method for testing the reliability of an apparatus for diagnosing breast cancer using the same and an apparatus for diagnosing breast cancer comprising the same. A mock breast tissue phantom and a mock cancer tissue phantom are provided. The mock breast tissue phantom is separated from a mock cancer tissue phantom. The mock breast tissue phantom and the mock cancer tissue phantom are formed by using a solvent or by mixing water and the solvent. A relational expression between the specific gravity of the solvent (b) and the specific gravity of the water (a) is (b-a)/a x 100. This value is -10 to +10 (except for zero).
Abstract:
PURPOSE: A microwave image restoring device and method thereof are provided to quickly obtain an effective initial estimation value by calculating values only few times. CONSTITUTION: A breast cancer diagnosing device comprises a tank into which a breast(210) is inserted. If a breast with cancer is inserted into the tank, the lengths of antennas are lengthened or shortened to set an initial length. An electromagnetic wave transceiver(232) receives the amplitude and phase information of an electromagnetic wave through sixteen input lines. The amplitude and phase information is measurement data necessary for restoring an image received through the antennas. The measurement dada is inputted to a display processing unit(246) through an image processing unit(238) and is converted into graphic data.

Abstract:
PURPOSE: A microwave tomogram image analyzer and a method thereof are provided to decipher a kind, a size and a location of a tumor in a body of a medical examined person accurately by analyzing dielectric constant data of a measurement object from a microwave tomography. CONSTITUTION: An operation unit(420) creates information of color bars and a contour type plane of the measurement object. The color bars digitally express a dielectric constant according to the color of the contour type plane view. A display controller(430) changes created information to graphic data. A display unit(440) displays using supported information of transformed graphic data. The operation unit supplies location information with a maximum dielectric constant, and a maximum dielectric constant on a contour type plane to the display controller.
Abstract:
PURPOSE: A breast cancer diagnosis apparatus is provided to reduce breast cancer diagnosis time by controlling flow rate and speed optionally and supplying a liquid efficiently. CONSTITUTION: A breast cancer diagnosis apparatus includes a fluid supply unit(500) and supply controllers(300,400). The fluid supply unit supplies the liquid, and the supply controller controls the flow rate from the fluid supply unit. The supply controller includes a flow rate sensor(41) and a controller(42). The flow rate sensor detects the flow rate and the controller controls the fluid supply unit based on the sensed data of the flow rate sensor.
Abstract:
A device and a method for checking vulnerability of network devices by using a search engine are provided to inspect a network device which has possibility that a subnet has vulnerability and check vulnerability with regard to the corresponding network device, thereby shortening time for checking vulnerability. A network structure checking module(211) generates network structure information by checking a structure of a system network(240). A control module(214) selects at least one subnet checking vulnerability based on network structure information. A vulnerable network device checking module(212) checks at least one check target network device for checking vulnerability in at least one subnet through a search engine(220). A vulnerability checking module(213) checks vulnerability about at least one check target network device. A checked result display module(215) receives the vulnerability check result and outputs the vulnerability.
Abstract:
A microwave imaging apparatus and method is provided to improve the accuracy of measurement data by reducing the interference between channels. A microwave imaging apparatus comprises a photoelectric converting device(310), an electric-photo converting unit(320), a transceiver(134b-134p) and control / treatment unit. The electric-photo converting device converts the oscillator signal into the optical signal. The electric-photo converting device converts the optical signal from the photoelectric converting device into the oscillator signal. The transceiver converts the radio frequency signal which passes through the imaging object by using the oscillator signal transformed with the electric-photo converting device into the IF(Intermediate Frequency) signal. A control/process unit process an intermediate frequency signal transformed with transceiver.
