In some operating rooms, surgeons wear headsets that overlay a patient's CT or MRI scans onto the body, like X-ray vision aligned to the anatomy.
AR surgical navigation overlays a patient's pre-operative CT or MRI scans onto the surgeon's live view, aligned to the actual anatomy in real time. This gives a kind of X-ray vision, showing bones, vessels, or tumors hidden beneath the surface, valuable for delicate spinal or brain work where millimeters matter.
Telegraphy sends coded messages over wires, an old unrelated technology, and photosynthesis is how plants convert sunlight into energy, entirely unrelated to surgery.
Because the overlay appears in the headset rather than a separate monitor, surgeons keep their hands and attention more continuously on the patient instead of glancing away.
