VTK is able to read raw files;  I wrote a free DICOM converter that might 
be used to convert medical images to a raw format. This is how I deal with 
medical images actually :

http://www.hds.utc.fr/~barre/dicom/dicom2/

There is a special section dedicated to its use regarding the Vtk :

http://www.hds.utc.fr/~barre/dicom/dicom2/how-to.html#Convert to raw

Check both sections:

    "Usage (1) -> Conversion -> raw"
    "How to -> Convert to raw (vtk)"

You might also have a look at the "bible" : The Medical Image Format FAQ

Hope it helps

...does not look good. There is no predefined file extension in the DICOM 
protocol (part 10). Sometimes '.dcm', but '.ima' is most often used in 
Siemens or GE proprietary format (i.e., not DICOM).

This is not a DICOM conformant header (part 10).
Neither does it look like a "less conformant" format like ACR/NEMA 2.0, 3.0 
(or pre-DICOM).
Sorry :)
