Temporal and spatial profiles of the ultrasound for modulating the MRCP. (A) The temporal waveforms of the pulsed tFUS triggered by the foot pedaling motion. (B-C) The lateral and axial views of the ultrasound focus and beam in free water measured with a 3D pressure scanning system. (D) The axial view of the transcranial ultrasound beam within a full real human skull sample. The smaller Z number along the axial view represents the shorter distance from the transducer’s acoustic exit plane.
