  • Patent number: 8083680
    Abstract: The present invention is directed to an ultrasound system and a method for reformatting a planar image. The ultrasound system includes a volume data acquiring unit and an image processing unit. The volume data acquiring unit may acquire volume data by transmitting/receiving ultrasound signals to/from a target object of an un-echoic area. The image processing unit may perform inverse volume rendering upon the volume data to form a 3-dimensional image showing the target object and set a region of interest (ROI) on the target object in response to a user input. The image processor detects data corresponding to the ROI from the volume data and reformats the detected data to form a planar image.
