(a) and (d): Schematic of a straight and a curved FUSs subjected to a point ultrasound source, respectively. The dashed lines plot the phase distribution of the ultrasound waves along the fiber. (b-c): Calculated spatial sensitivities of a straight FUS in x-z plane and x-y plane. (e-f) Calculated spatial sensitivities of a curved FUS in x-z plane and y-z plane.
