体数据模型剪切Volume clip with Model(Wiki)

image Volume Clip With Model(Wiki)


  • Volume clip with model(体数据模型剪切法)

    Removes volume contents inside or outside the selected surface model

    移除选定曲面模型内部或外部的体数据内容

    User may define and dynamically edit a 3D clipping surface by markup points (uses Delaunay triangulation, therefore it mostly generates convex surfaces)

    用户可以通过标记点定义和动态编辑3D裁剪表面(使用Delaunay三角剖分算法,因此它主要生成凸曲面)

    For incremental clipping select the input volume also as output volume

    对于增量裁剪,请将输入体数据也作为输出体数据


Clip irrelevant image areas of the input volume before segmentation

分割前剪切输入体数据的无关图像区域


  • Go to Volume clip with model module (进入体数据模型剪切模块)

  • Set(设置):

    Input volume: your input image

    输入体数据: 你要输入的图像

    Clipping surface: Create new model

    剪切表面:创建新的模型

    Clipping surface from markups: Create new MarkupsFiducial

    以标记点剪切表面:创建新的标记基准点

    Clip outside: uncheck

    剪切外面区域:取消选中

    Fill value: background voxel value (depending on your imaging modality it may be -1000, 0, or other)

    填充体素值:背景体素值(取决于你的成像模式,它可以是-1000,0,或其他)

    Output volume: Create new volume

    输出体数据:创建新的体数据

    Drop/move a few markup fiducials around the image areas that you would like to remove

    在将要删除的图像区域周围放置/移动一些标记基准点

    Click apply

    点击应用


  • If there are more areas to remove then set the created Volume node as Output volume and repeat the following steps

  • 如果有更多区域要移除,请将创建的体数据节点设置为输出体数据,然后重复以下步骤

    Set: Clipping surface from markups: Create new MarkupsFiducial (or go to the Markups module to remove all fiducials from the current list)

    设置:以标记点剪切表面:创建新的标记基准点(或去Markups模块从当前列表中删除所有的基准点)

    Drop/move a few markup fiducials around the image areas that you would like to remove

    在要删除的图像区域周围放置/移动一些标记基准点

    Click apply

    点击应用


Create quick mask for registration

为配准创建快速蒙版


  • Go to Volume clip with model module (进入体数据模型剪切模块)

  • Set(设置):

    Input volume: your input image

    输入体数据: 你输入的图像

    Clipping surface: Create new model

    剪切表面:创建新的模型

    Clipping surface from markups: Create new MarkupsFiducial

    以标记点剪切表面:创建新的标记基准点

    Output volume: Create new volume

    输出体数据:创建新的体数据

    Drop/move a few markup fiducials around your region of interest on 2-3 orthogonal slices (3-4 fiducials on each slice should be enough)

    在2-3个相互垂直的切片上的感兴趣区域周围放置或移动一些标记基准点(每个切片上放置3-4个基准点应该足够了)

    Click apply

    点击应用

  • Set(设置):

    Input volume: Volume (the mask volume that you created)

    输入体数据:体数据(您创建的蒙版体数据)

    Clip outside: uncheck

    剪切外面区域:取消选中

    Fill value: 100

    填充体素值:100

    Click apply

    点击应用
