Cardiac surgery is one of the most difficult procedures, and it gets even more complex when it comes to operating on tiny children’s hearts. Visualization techniques like cinematic rendering provide a detailed 3-D view of the patient’s heart and surrounding anatomy. But what happens when these images are turned into a hologram that can be rotated, zoomed, and looked at from all possible perspectives?

Alkassar’s moment of truth

This is Dr. Alkassar’s reaction as he tried out the HoloLens with Cinematic Rendering for the first time. In the background on his computer screen you can see what he sees through his HoloLens, but in 3D, he is able to zoom in an out of structures, turn them around, and observe them from every possible angle.
