    • An image data processor processes 3D mesh data to identify an object boundary by, identifying for a first line segment between first and second points of the mesh, third and fourth points lying either side of the line segment, the first, second and third points comprising a first triangle and the first, second and fourth points comprising a second triangle. The image data processor determines a first normal vector for the first triangle and a second normal vector for the second triangle, determines a third normal vector perpendicular to a display screen, determines a first product of the first and third vectors and a second product of the second and third vectors and identifies the first line segment as a potential segment of the object boundary in response to the sign of the first and second products.
    • 图像数据处理器通过以下步骤处理3D网格数据以识别对象边界:识别网格的第一和第二点之间的第一线段,位于线段的任一侧的第三和第四点,第一,第二和第三点包括 第一三角形和包括第二三角形的第一,第二和第四点。 图像数据处理器确定用于第一三角形的第一法线向量和第二三角形的第二法向矢量,确定垂直于显示屏幕的第三法线矢量,确定第一和第三矢量的第一乘积以及第 第二和第三矢量,并且响应于第一和第二乘积的符号,将第一线段识别为对象边界的潜在段。

    • A system automatically detects objects in an image and automatically displays a chosen object if the object is not currently visible in real time. An image data processing system automatically displays potentially hidden features in 3D (three dimensional) medical image data. A repository includes a 3D (three dimensional) image dataset representing an anatomical volume of interest. An image data processor processes the dataset retrieved from the repository by, (a) automatically detecting if a first object is obscured by a second object in the 3D image dataset, (b) automatically determining if the first object is visible by rotating the anatomical volume of interest and (c) rotating the anatomical volume of interest until the first object is visible in response to a command. A display processor initiates display of the rotated anatomical volume of interest.
    • 系统自动检测图像中的对象,如果对象当前不可见,则自动显示所选对象。 图像数据处理系统在3D(三维)医学图像数据中自动显示潜在的隐藏特征。 存储库包括表示感兴趣的解剖体积的3D(三维)图像数据集。 图像数据处理器通过以下步骤处理从存储库检索的数据集:(a)自动检测第一对象是否被3D图像数据集中的第二对象遮挡,(b)通过旋转解剖体积来自动确定第一对象是否可见 感兴趣的和(c)旋转感兴趣的解剖体积,直到响应于命令第一对象是可见的。 显示处理器启动所感兴趣的旋转的解剖体积的显示。
