I found the code for extracting skin in the following url,But how do I import my own DICOM data instead of using the MRHEAD example?

Hi Yingxin

Did you solve it? I need to extract skin from CT images, not sure whether we have the same problem.

Best regards,  
Chuan

Open the python console  
change the following code to your data name,

and then paste it in the console to run.

```auto
masterVolumeNode = slicer.util.getNode('你自己的数据名称')

segmentationNode = slicer.mrmlScene.AddNewNodeByClass("vtkMRMLSegmentationNode")
segmentationNode.CreateDefaultDisplayNodes() # 用于展示
segmentationNode.SetReferenceImageGeometryParameterFromVolumeNode(masterVolumeNode)
addedSegmentID = segmentationNode.GetSegmentation().AddEmptySegment("skin")

segmentEditorWidget = slicer.qMRMLSegmentEditorWidget()
segmentEditorWidget.setMRMLScene(slicer.mrmlScene)
segmentEditorNode = slicer.mrmlScene.AddNewNodeByClass("vtkMRMLSegmentEditorNode")
segmentEditorWidget.setMRMLSegmentEditorNode(segmentEditorNode)
segmentEditorWidget.setSegmentationNode(segmentationNode)
segmentEditorWidget.setMasterVolumeNode(masterVolumeNode)

segmentEditorWidget.setActiveEffectByName("Threshold")
effect = segmentEditorWidget.activeEffect()
effect.setParameter("MinimumThreshold","35")
effect.setParameter("MaximumThreshold","695")
effect.self().onApply()

# 平滑
segmentEditorWidget.setActiveEffectByName("Smoothing")
effect = segmentEditorWidget.activeEffect()
effect.setParameter("SmoothingMethod", "MEDIAN")
effect.setParameter("KernelSizeMm", 11)
effect.self().onApply()

segmentEditorWidget = None
slicer.mrmlScene.RemoveNode(segmentEditorNode)

segmentationNode.CreateClosedSurfaceRepresentation()

```
