Abstract
Systems and methods for safety assessment before and during a transcranial ultrasound (TUS) procedure are described. A neuronavigation system is used to determine the probe's position and orientation. The probe's location and the subject's head MRI data are used to simulate the acoustic field within the subject's head. The acoustic field is overlaid on the MRI data and displayed to a clinician for evaluation. The phases of the transmit voltages are adjusted to optimize the location of the peak of the acoustic field to match the targets in the subject's brain. Before and during TUS, the spatial distribution of tissue temperature, MI, TIC, and Iare computed and displayed to the clinician. Acoustic field changes due to the subject's movement are detected, and the TUS operation is terminated if the stimulated acoustic field becomes off-target. Monitoring circuits shut down the neuromodulation if parameters are out-of-range.
