  1. For a number of dMRI formats we recommend use of the DICOM to NRRD converter before loading the data into Slicer.
  2. Image volumes, RT structure sets, dose volumes, etc. can be exported using DICOM module's export feature. Limited support for writing image volumes in DICOM format is provided by the Create DICOM Series module. Support of writing DICOM Segmentation Objects is provided by the Reporting extension
  3. According to MetaIO naming scheme DICOM 'LPS' direction is 'RAI'.

What if your data is not supported?

If you have a file of binary data and you know the data is uncompressed and you know the way it is laid out in memory, then one way to load it in Slicer is to create a .nhdr file that points to the binary file.

A way to get started is to download sample data that is similar to your data (e.g. a CT or MR). Then save that data in .nhdr format and start editing the file to match your data.

Refer to the NRRD format documentation to see what the keys mean.
