To disambiguate ultrasound imaging and adapt to the neurosurgeon's surgical objective, a patient-specific real-time network is trained using synthetic ultrasound data generated by simulating virtual iUS sweep acquisitions in pre-operative MR data.

This advantage is pronounced for subjects with tumors that affect the language areas and thus cause spatial reorganization of the functional regions.
