A clinic in Germany started experimenting with an application using augmented reality on iPads in the OR. During operations, surgeons can see through anatomical structures such as blood vessels in the liver without opening organs therefore they can perform more precise excisions.
A CT scan is performed before the surgery and the imaged vessels are identified within software, all of which is then transferred to the iPad. During the procedure the surgeon can navigate the imaged liver to see where the vessels are, and if the camera is turned on and pointed at the exposed liver the app automatically superimposes the vessel structure of the organ onto the live picture. Notably, the app is not simply a concept, but was already tested successfully during a liver tumor removal at Asklepios Klinik Barmbek in Hamburg.
Years ago, I wrote about an experiment of similar kind performed at the Computer Assisted Medical Procedures Institute at the Technische Universitat München.
The technology is now there, we just have to put evidence behind using it in practice. Exciting times ahead!
