    • 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. MPR image data is generated by extracting each voxel of the volume data corresponded to each of three MPR cross-sectional planes that are mutually orthogonally crossing at the reference point and displayed with the virtual endoscopy image data.
    • 基于从对象获取的体数据,同时获取诊断对象区域的虚拟内窥镜图像数据和多平面重构(MPR)图像数据的超声诊断系统,医疗用图像显示装置及显示方法。 虚拟内窥镜图像数据通过在从对象获取的体数据上设置观察点和观察方向来生成。 在用于建立观察方向的虚拟内窥镜图像数据中所示的管腔器官的目标区域上设置有标记。 沿观察方向设置从音量数据开始的参考线。 通过将与参考线交叉的体积数据的体素值与规定的阈值进行比较,将诊断对象区域的表面与基准线交叉的参考点设定为体积数据。 MPR图像数据是通过提取与参考点相互正交交叉并与虚拟内窥镜图像数据一起显示的三个MPR横截面中的每一个对应的体数据的每个体素来生成的。
