The study will happen in two stages. First, surgeons will perform a cerebral angiogram while using the standard display technology in the operating room. During this step, the contents of the large monitor will be recorded using a specialized capture device. In the second stage of the study, surgeons will watch the previously captured video from the monitor in the angiography suite using MR in a simulated surgical field. Participants will have the flexibility to select specific windows from the larger external monitor display and strategically position them in the air around them. As they view the recorded surgery, they will interact with these monitors as though they are performing the recorded surgery in real-time. This immersive approach simulates a live surgical experience, allowing us to closely observe and analyze how MR technology can enhance surgical performance and decision-making in a dynamic, virtual setting. Following the complete playback of the surgical video, surgeons will be asked a series of semi-structured interview questions to gauge their experience with the MR display and its impact on the surgical workflow.
