是不是可以开发自动boundingbox功能呢?如果能够 oriented bounding _box_ 就太好了…

This feature is already available in Segment Statistics module. See complete example [here](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#get-size-position-and-orientation-of-each-segment).

我用这个示例做了pedicle的obb，又用以下代码crop volume：

> I used this example [here](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#get-size-position-and-orientation-of-each-segment)to make the obb of the pedicle, and also used the following code to crop the volume:

`cropLogic = slicer.modules.cropvolume.logic() crop_module = slicer.vtkMRMLCropVolumeParametersNode() crop_module.SetROINodeID(roi.GetID()) crop_module.SetInputVolumeNodeID(volume.GetID()) crop_module.SetVoxelBased(True) cropLogic.Apply(crop_module) `

却得到了下面我不想要的结果（注意：红色的是得到的obb）：

> But I get the following result that I don’t want(Note: the red one is the obb):

好吧，解决了。。。
