Abstract
Systems and methods provide a neurosurgeon with real-time feedback on safety of prospective surgical trajectories, which can simultaneously reduce surgical intervention times and improve patient safety. Examples can determine a level of safety for a prospective surgical trajectory by determining a number of times that a prospective surgical trajectory representation (e.g., a 1D line representing a prospective surgical trajectory) intersects (a) a patient-specific 3D cortical surface representation (i.e., a 3D representation representing an exterior surface of the patient's brain cortex); and (b) one or more patient-specific 3D hazard brain region representations (e.g., 3D representations representing hazard brain regions of the patient to be avoided during surgery).
