Dear Slicer Users,  
we have waveforms from 4DCT stored as DICOM files. I am wondering if there is any option in Slicer how to visualize them. I have never work with “non-image” DICOM till now and I am little bit lost 🙂  
Thank you for any suggestions!

Lukas

I don’t think we have anything for that data type right now, but it would be great if someone could write a [DICOMPlugin](https://slicer.readthedocs.io/en/latest/developer_guide/modules/dicom.html#plugin-architecture) that could handle them. It should be relatively straightforward.

Dear Steve,thank you for quick respond. I tried to find solution somewhere else without success. Even this type of DCM seems to very common in radiotherapy. If someone would be interested in this,I can share some example.  
Thanks!
