While looking for medical podcast I ran accross a very interesting way iPods are being used by radiologists.

Radiologists are using iPods to store medical images. Dr. Ratib and Antoine Rosset, M.D., a radiologist in Geneva, Switzerland, recently developed OsiriX, Macintosh-based software to display and manipulate of medical image data.

"Radiologists deal with a very large amount of medical imaging data," Dr. Ratib explains. "I never have enough space on my disk, no matter how big my disk is—I always need more space. One day I realized, I have an iPod that has 40 gigabytes of storage on it. It's twice as big as my disk on my laptop and I'm using only 10 percent of it for my music. So, why don't I use it as a hard disk for storing medical images?"

Normally, radiologists rely on specialized workstations, costing $100,000 each, to view high resolution 3D images. Dr. Ratib says the iPod platform "has similar functionality [to the high-end workstations], it's accessible to the rset of the medical community and you don't have to spend $100,000,$200,000 to view images."
