<div>You can still get at this information. We store all dicom tags in the meta data dictionary for the image. Look at the dicom processing examples in Examples/IO to see how to get the meta data dictionary. Once you have it, you can use the ExposeMetaData method to get the values for a given tag.

I have looked in the DICOM and the spacing is in (0x3002,0x0011) and the position is in (0x3002,0x0012). This is probably the issue - it handles normal images not DICOM RT images.
