Wow! That is all that I can say! I saw this clip on Dr. Dalai's blog and I was blown away by MiMVista. It is a viewer application for the iPhone that allows you to view CT, MRI, etc.
I think this may just be the next killer app for radiology. As they say in the clip, imagine sitting with your patient showing them the images. The iPhone seems to be bringing a whole lot to the table for medical applications. I also liked the concept of the anatomy application that was shown in the first half of the clip.
