  • Patent number: 9414807
    Abstract: An ultrasound diagnosis system, a medical image display apparatus and displaying method that simultaneously acquires virtual endoscopy image data and multi-planar-reconstruction (MPR) image data of a diagnosing target region based on the volume data acquired from an object. Virtual endoscopy image data is generated by setting up a viewing point and a viewing direction on a volume data acquired from the object. A marker is provided on a target region of a lumen organ shown in the virtual endoscopy image data for setting up an observing direction. A reference line started from the volume data is set up along an observing direction. By comparing a voxel value of the volume data that is crossing to the reference line with a prescribed threshold value, a reference point where a surface of the diagnosing target region crosses the reference line is set up to the volume data.
