  • Patent number: 10702243
    Abstract: An ultrasound diagnosis apparatus including: an image processor configured to acquire ultrasound data of an object; a controller configured to generate a wearable signal carrying information corresponding to a difference between the acquired ultrasound data and reference ultrasound data; and a communication module configured to transmit the wearable signal to a wearable device. The wearable signal is acquired by comparing the ultrasound data with the reference ultrasound data and includes information about the difference between the ultrasound data and the reference ultrasound data.

  • Patent number: 10130312
    Abstract: Disclosed herein is a medical imaging apparatus and a control method for the same, particularly a technology configured to correct and convert medical image data. Therefore, based on medical image data acquired by a medical imaging apparatus performing medical imaging diagnosis, an image having the same quality as an image outputted on a display unit of the medical imaging may be outputted on other display device. The medical imaging apparatus includes a medical image acquisition unit acquiring medical image data of an object and a memory unit storing output image information of display device and display device information including the type of display device outputting a medical image of the object.

  • Publication number: 20160157823
    Abstract: Disclosed herein are an ultrasound diagnostic apparatus and a control method for the same, and more particularly, an apparatus to audio-visually inform information on the actions needed to be taken by a patient at the time of an ultrasound diagnosis. In accordance with one aspect of the present disclosure, an ultrasound diagnostic apparatus includes a storage unit at which data of actions of a patient needed to be taken at the time of an ultrasound diagnosis is stored; a processor to determine a type of an ultrasound probe or a diagnostic mode provided to perform an ultrasound diagnosis and select from the data of actions stored as the above the data of action to be taken by the patient on the basis of the type of the ultrasound probe or the diagnostic mode determined as the above; and at least one display unit to display the selected data of action to be taken by the patient.

  • Patent number: 8303928
    Abstract: The present invention relates to a fluorine-containing magnesium oxide powder using a vapor phase reaction and a method of preparing the same and more particularly to a fluorine-containing magnesium oxide powder brings about a cathode-luminescence emission having a peak within a wavelength range of 220 to 320 nm upon being excited by electron beams. The present invention provides a fluorine-containing magnesium oxide powder using a vapor phase reaction that sprays fluorine-containing gas and oxygen-containing gas to magnesium vapor, and the purity of magnesium oxide containing fluorine (i.e. the purity of fluorine-containing magnesium oxide) of 0.001 to 2 wt % is at least 98 wt % and a BET specific surface area thereof is 0.1 to 50 m2/g.
