Tug,
Sounds like you got a deal. Often times, the medical files are proprietary and you would have to have the originating software to open and read files. In your case, the hospital has the originating product, and the doctors office may have a "read only" set of software. In that case you would not likely be able to get it open and have anything viewable.
In our lab we often get request for copies of our raw data that the patient wants to take home. I always tell them that I would be happy to make a copy for them but they will need a $10,000 software program to see all those wavey lines. Usually at that point they are OK with just taking the printed reports and some indicative segment prints.
Granted that is not the same as having copies of Xray, MRI, CT's. PET's Ultrasound or even EKG's but it's "how the system works sometimes"
