  • Method of obtaining a magnetic resonance image in which the streak artifacts are corrected using non-linear phase correction
    Patent number: 7719274
    Abstract: A non-linear phase correction method is provided. For the non-linear phase correction method, image information is acquired by gradient echo echo planar imaging (EPI). Reference information is acquired by spin echo EPI. The image information is corrected based on the reference information.
    Type: Grant

  • Brain Wave Measuring Method, Apparatus And Computer Readable Recording Medium Implemented With Program For Executing The Method
    Publication number: 20080234596
    Abstract: A method for measuring a brain wave comprises extracting positive and negative peaks from an electrocardiogram (EKG) signal reflecting heartbeat information, and positive peaks from an electroencephalogram (EEG) signal reflecting heartbeat-caused noise information and brain wave information. The positive peaks of the EEG signal are classified into a first peak group and a second peak group based on the positive peaks of the EKG signal. The first peak group is affected more greatly by the heartbeat than by the brain wave, and the second peak group is affected more greatly by the brain wave than by the heartbeat. Noise of the first and second peak groups is removed from the EEG signal.
