image Panels and their use（面板及用法）

  • Segmentation: Choose the segmentation to edit
  • 分割：选择要进行编辑的分割

  • Master volume: Choose the volume to segment. The master volume that is selected the very first time after the segmentation is created is used to determine the segmentation’s labelmap representation geometry (resolution, axis directions, origin). The master volume is used by all editor effects that uses intensity of the segmented volume (e.g., thresholding, level tracing). The master volume can be changed at any time during the segmentation process.

  • 主体数据：选择要进行分割的体数据。 创建分割后第一次选择的主体数据是用来确定分割标签图的几何表达（分辨率，轴方向，原点）。 主体数据由分割体数据的强度编辑工具所使用（例如阈值，套索）。 主体数据在分割过程中可随时更改。

  • Note: Currently the only way to change geometry is to create a new segmentation, set its geometry, and then import segments from another segmentation.

  • 注意：目前更改几何图的唯一方法是创建新的分割并设置几何图，然后从另一个分割中导入分割体。

  • Add segment: Add a new segment to the segmentation and select it.

  • 添加分割体：加入一个新的分割体到分割并选择它。

  • Remove segment: Select the segment you would like to delete then click Remove segment to delete from the segmentation.

  • 删除分割体：选择您要删除的分割体然后单击从分割中将之删除。

  • Create Surface: Display your segmentation in the 3D Viewer. This is a toggle button. When turned on the surface is created and updated automatically as the user is segmenting. When turned off, the conversion is not ongoing so the segmentation process is faster. To change surface creation parameters: go to Segmentations module, click Update button in Closed surface row in Representations section, click Binary labelmap → Closed surface line, double-click on value column to edit a conversion parameter value. Setting Smoothing factor to 0 disables smoothing, making updates much faster. Set Smoothing factor to 0.1 for weak smoothing and 0.5 or larger for stronger smoothing.

  • 创建曲面：在3D视窗中显示您的分割。这是一个在用户分割时打开自动创建和更新表面的切换按钮，在关闭时不进行转换而加速分割过程。要更改曲面创建参数：转到分割模块（Segmentions ），在状态（Representations）窗口列表中点击“关闭曲面”行中的“更新”按钮，单击“Binary labelmap →关闭表面行，双击列的值编辑转换参数值，将平滑系数设置为0将禁用平滑以使更新更快，将平滑系数设置为0.1以实现弱平滑，将平滑系数设置为0.5以获得增强的平滑。

  • Segments table: Displays list of all segments. - Eye icon: Toggle segment’s visibility. To customize visualization: either open the slice view controls (click on push-pint and double-arrow icons at the top of a slice viewer) or go to Segmentations module. - Color swatch: set color and assign segment to standardized terminology.

  • *分割表：显示所有分割体的列表。 - 眼睛图标：切换分割体的可见性。 自定义可视化：打开切片视图控件（在切片视窗的顶部单击图钉图标并双击箭头图标）或转到分割模块。 - 色样：设置颜色并分配分割体使之标准化。

  • Effects: Select the desired effect here. See below for more information about each effect.

  • 效果：在这里选择所需的效果。有关每种效果的更多信息，请参阅下文。

  • Options: Options for the selected effect will be displayed here.

  • 选项：所选效果的选项将显示在此处。

  • Undo/Redo: The module saves state of segmentation before each effect is applied. This is useful for experimentation and error correction. By default the last 10 states are remembered.

  • 撤销/重做：模块在应用每个效果之前保存分割状态。 这对于实验和纠错非常有用。 默认情况下会记住最后的10个状态。

  • Masking: These options allow you to define the editable areas and whether or not certain segments can be overwritten.

  • 掩膜：这些选项允许您定义可编辑区域以及某些分割是否可以被覆盖。

    • Editable area: Changes will be limited to the selected area. This can be used for drawing inside a specific region or split a segment into multiple segments.

    • 可编辑区域：更改将限于所选区域。 这可以用于在特定区域内进行绘制或将分割体分割为多个分割体。

    • Editable intensity range: Changes wil be limited to areas where the master volume’s voxels are in the selected intensity range. It is useful when locally an intensity threshold separates well between different regions. Intensity range can be previewed by using Threshold effect.

    • 可编辑的强度范围：更改将限制在主要体数据的体素处于选定强度范围内的区域。 当局部强度阈值在不同区域之间良好地分离时，它是有用的。 可以使用阈值工具预览强度范围。

    • Overwrite other segments: Select which segments will be overwritten rather than overlapped.

    • 覆盖其他切割体：选择哪些切割体将被覆盖而不是重叠。

      • All segments: Segment will not overlap.

      • 全部切割体：切割体不会重叠。

      • Visible segments: Visible segments will not overlap with each other. Hidden segments will not be overwritten by changes done to visible segments.

      • 可视切割体：可视切割体不会相互重叠。隐藏切割体不会被可视切割体所做的更改覆盖。

      • Note: Segments can overlap. Changing one segment will not change any other.

      • 注意：切割体可以重叠。改变一个切割体不会影响另外一个。
