Technique For Determining A Visualization Based On An Estimated Surgeon Pose

A method, a system, and a computer program for determining a visualization of content to be displayed to a surgeon on a display of a portable display device are provided. First pose data indicative a first pose of an anatomical feature of a patient in an operating room and second pose data indicative of a second pose of a portable display device in the operating room are obtained. Based on the first pose data and the second pose data, a third pose of a surgeon relative to the patient is estimated. Based on the estimated third pose, a visualization of content to be displayed to the surgeon on a display of the portable display device is determined.
