[vtkusers] DICOM reader

[Patrick D. Emond]

Hello,

I'm using vtkDICOMImageReader with the SetDirectoryName() function to 
load a bunch of images in a single directory.  Is there any way to 
determine if there are any valid DICOM files in the selected directory? 
  The only way I see of doing this is to update the image reader and 
check if the data increments are (1, 1) or not.  Is there a better way 
of doing this?

Just to be clear, I'm not looking for a CanReadFile() method, since this 
method can only detect if a single file is readable, not a list of files 
in a directory.

Cheers,
Patrick
