  • Microchip for analyzing nucleic acid and method of nucleic acid analysis using the same
    Patent number: 9017941
    Abstract: A method for nucleic acid analysis including injecting a slight amount of nucleic acid sample for analysis, characterized in that most of a nucleic acid sample which is not used, excluding the slight amount of the nucleic acid sample which is used for analysis, can be obtained as a pure product which is not contaminated with a fluorescent material, and a microchip for analyzing nucleic acid which enables such method for nucleic acid analysis, are provided. The method for nucleic acid analysis may analyze at least two different nucleic acid samples in a continuous manner by sequentially injecting the at least two different nucleic acid samples.
    Type: Grant
    Filed: March 7, 2013
    Date of Patent: April 28, 2015
    Assignee: Postech Academy-Industry Foundation
    Inventors: Jong Hoon Hahn, Byoung Joo Kwak, Han-Ok Kim

  • Apparatus and method for forming 3D ultrasound image
    Patent number: 7507204
    Abstract: The present invention relates to a 3D ultrasound diagnostic forming a 3D ultrasound image only with volume data exiting within contour by automatically detecting the contour of a target object, comprising: a first unit for generating a region of interest (ROI) box on a 2D ultrasound image; a second unit for detecting a contour of a target object in the ROI box; and a third unit for forming a 3D ultrasound image by rendering volume data existing in the detected contour.
