Abstract: A method for surgical trajectory planning, particularly useful for deep brain stimulation. A three-dimensional model of an anatomical structure is rendered, which includes a target site. As the user gazes into the model, eye tracking data is obtained and a line of sight for the target site is identified. A surgical trajectory is determined along the line of sight between the target site and a surgical entry point on the surface of the anatomical structure. The method allows the identification of an optimal surgical trajectory to reach the target site while avoiding key structures within the anatomical structure, such as blood vessels, sulci, ventricles. Advantageously, the model is rendered in a virtual environment, and the eye tracking data is obtained from a VR headset.
