Operating system:windows 10  
Slicer version:4.11.0  
Expected behavior:  
Actual behavior:  
Hi all  
I have installed 3D slicer 4.11.0 & its extension package but I have many problems!  
The phantom image is in DICOM format & 21 3ddose files resulting dosxyznrc.  
Can I use 3D slicer for calculating DVH?  
I can load my phantom and 3ddose files by choosing item “load file”.  
Nevertheless, I am not sure that is correct or not?  
I mean ,dose not loading 3ddose files need any preprocessing in 3D silcer?  
In addition , for plotting DVH I have to contour organs but I could not find contour module!!  
where is the contour module?

I hope that you can help me.  
Thanks in advance.

After you install the SlicerRT extension from the Extension Manager, you can load 3ddose files using drag&drop or the load file menu. Also you will find the Dose Volume Histogram module in the Radiotherapy category.

For more infor see doc: [https://www.slicer.org/w/index.php/Documentation/Nightly/Extensions/SlicerRT](https://www.slicer.org/w/index.php/Documentation/Nightly/Extensions/SlicerRT)
