  • Patent number: 10209333
    Abstract: A flipped fitting method that performs a flipped curve fitting on a maximum of 256 MRI images obtained at different echo times using an EPI image which obtains a plurality of MRI images at a plurality of different echo times within a TR period after application of an excitation RF pulse. Then, T2* values are fitted based on a sufficient amount of acquired TE images, such that it is possible to provide much more accurate T2* values than these provided by underestimated or overestimated fitting by the existing method which is based on only 12 images and to obtain rapid and accurate data without nerve stimulation or acoustic noise. Further, the flipped fitting method is more suitable and accurate for showing the real T2* values.

  • Publication number: 20170135589
    Abstract: According to the present invention, accurate T2* and vascular images are concurrently acquired by acquiring a T2* image without a flow compensation and a T2* image with a flow compensation and subtracting the two images to reconstitute an image showing the flow phenomenon. Furthermore, an accurate T2* image can be acquired by using the readout gradient without the flow compensation and also the accurate T2* and vascular images can be concurrently acquired. The clinical judgment for blood flow rate of the blood vessel and the clinical judgment for acute stroke can be concurrently made, and so the present invention can be widely utilized in clinical practice.

  • Publication number: 20170119275
    Abstract: Images where the vascular walls are automatically divided are obtained by obtaining two MRI images that reflect different properties of the blood vessel and obtaining the difference between the two images. This can image both the vascular inner and the outer walls, thereby obtaining the exact size of the blood vessel, and the thickness between the vascular inner and outer walls. Therefore, it is possible to stably perform the operation using a stent with an accurate size during the stent procedure.

  • Patent number: 9606211
    Abstract: A first off resonance radio frequency (RF) pulse and a second off resonance RF pulse having a phase difference of 180 degrees from the first off resonance RF pulse are applied, one or more auxiliary gradient magnetic fields for offsetting inhomogeneity of a main magnetic field generated by applying the first and second off resonance RF pulses are applied, and magnitudes and signs of the auxiliary gradient magnetic fields are appropriately adjusted. Therefore, artifacts generated due to inhomogeneity of a main magnetic field in an imaging method using an off resonance RF pulse may be removed. When this method is applied to an imaging method using a spatial pre-saturation RF pulse, the phenomenon in which spins excited by the pre-saturation RF pulse are excited again by the off resonance RF pulse to return signals, such that undesired signals overlap and appear in an ultimately-obtained signal, may be removed.

  • Patent number: 7778700
    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.
