在Slicer中添加点、直线和曲线

添加点

        markupsNode = slicer.mrmlScene.AddNewNodeByClass("vtkMRMLMarkupsFiducialNode")
        markupsNode.SetName('P')
       
        DisplayNode=markupsNode.GetDisplayNode()
        DisplayNode.SetSelectedColor(0,0,1)

        #AddControlPoint添加的是RAS坐标
        n = markupsNode.AddControlPoint([-0.5, 29.1, 29.1])
        markupsNode.SetNthControlPointLabel(n, "point1")

        n = markupsNode.AddControlPoint([-0.5, 29.1, 14.5])
        markupsNode.SetNthControlPointLabel(n, "point2")

添加直线

        lineCorNode=slicer.mrmlScene.AddNewNodeByClass("vtkMRMLMarkupsLineNode")
        lineCorNode.SetName('L')


        dispalyNode=lineCorNode.GetDisplayNode()
        dispalyNode.SetSelectedColor(0,0,1)

        lineCorNode.AddControlPoint([-0.5, 29.1, 29.1])
        lineCorNode.AddControlPoint([-0.5, 29.1, 14.5])

添加折线

        curveNode=slicer.mrmlScene.AddNewNodeByClass("vtkMRMLMarkupsCurveNode")

        curveNode.AddControlPoint([-0.5, 29.1, 29.1])
        curveNode.AddControlPoint([-0.5, 8.1, 9.8])
        curveNode.AddControlPoint([-0.5, -7.2, 18.2])
