OT: Image database software for EKGs

[Skrawny]

You guys seem to know a lot about a lot (or think you do ) so I figured I'd take a shot here...

My project:
------------------------------------
I have a huge stash of EKGs that I would like to scan and organize as a teaching/learning tool for med students, residents and fellows.

I have been given a new 320 G peripheral hard-drive on which to place them

What I would like is a program that would organize them all.
I don't need imaging editing functionality.
I would like it to be easy enough for a med student to sit in front of and figure out how to use
I would like it to be able to hierarchically categorize the EKGs but also be able to search by keyword (Boolean logic would be nice too if possible). (eg: search for inferior MI AND heart-block)

I have used Photoshop extensively and I like their organizer for my photos (which I know is available alone as freeware as Adobe Photoshop Album) but it only does limited keyword searches.

Anyone have any suggestions?
Thanks,
