It's hard to tell from the video, but it looks like the Medtronic would not fit through a stand doorway nor does it use regular 110ac. Both are things that seperate the DVIS from the competition in addition to the Medtronic not doing real-time.
As per my radiologist frind ,real time 3d will be very usefull in Arterial Embolization ...which is a medical procedure getting very popular to treat different types of tumor. at preset 2d fluoroscopy is used in this procedure ..which has lots of bottlenecks...and can be perform only on some tumors depending upon their location ...but real time 3d can do wonder to this procedure.....
