Hi,
Yes, I have been doing quite a bit of work in the DICOM area. Some of the most useful resources I have come across are as follows:

* Overview of DICOM files and some useful links
http://www.psychology.nottingham.ac....cr1/dicom.html

* Java source code from freeware software ImageJ for loading of DICOM files.
http://rsb.info.nih.gov/ij/docs/source/index.html

* DICOM sample files for testing
http://www.barre.nom.fr/medical/samples/

These are probably some of the best resources if you are just starting out in the field of DICOM.

Tony.
