  • Method for measuring change of cell in real time and device therefor
    Patent number: 11378534
    Abstract: Provided are a method and a device capable of: generating a first alternating current magnetic field passing through a chamber having a cell disposed therein, by using a plurality of primary coils arranged on a first plane; receiving a second alternating current magnetic field by using a plurality of secondary coils arranged on a second plane; and measuring an impedance change of a cell by using the first alternating current magnetic field and the second alternating current magnetic field.

  • Biological brain age calculation device and calculation method therefor
    Patent number: 10548507
    Abstract: A biological brain age is calculated by measuring a brain cortex thickness of each region in a brain MRI image of a person to be examined, and comparing the measured brain cortex thickness with normal control group information. A device for calculating the biological brain includes an image information input unit to input an MRI brain image of a person to be examined, a brain age calculation control unit to control a biological brain age calculation operation of the person to be examined based on the MRI brain image, a brain thickness measuring unit to measure a brain cortex thickness of each region in the MRI brain image, and a brain age calculating unit to match the measured brain cortex thickness with a normal range of brain thickness of each age, and calculate a biological brain age of the person to be examined.
