I really don’t know! For example we have an MRI unit right now at the Health Sciences Center. One of the only ones in North America, let alone the world, that actually can move. It’s an MRI unit that can move between three separate rooms. It can be in an angiography suite, which is where we do the vessel imaging, it can be on its own just to do general imaging and it can also move into an OR suite. So it can also be used in the operating room. They’re just starting to use it now. So it’s innovative but by the time that we got it in there was already a new one down on the market. So everything is changing constantly.
