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 [http://teem.sourceforge.net/nrrd NRRD format documentation] to see what the keys mean.
