Medical imaging is not like the JPGs you shoot with your camera. It uses a specialized format and transfer protocol called DICOM. DICOM compatible backup systems cost a lot of money ($25k on the low end, or $3 per exam).
We've created a cloud service that is more cost effective for small to medium sized health care providers and gives the simplicity only the web can offer.
We applied to the summer round for YComb, but I pulled the application because I felt we weren't quite ready. We're hoping PG and co will take a look later this year.
What do you think?
I was about to suggest some kind of plugin for OsiriX, but then I looked in your Help section and saw that one is already in the works...
What is needed is more open source options for PACS, especially servers, and your service may play a role in making things reasonable. OsiriX is very nice but unfortunately OS X only.
Also, it might be interesting to integrate this with remote image reading applications used by consulting/remote radiologists, since the images will already be "in the cloud".
