Fig. 2: Characterization of holograms by simulation and measurement.
From: Acoustic hologram-enabled simultaneous multi-target blood-brain barrier opening (AH-SiMBO)
a The simulated and measured acoustic field of holograms 1, 2 and 3 with different focal lengths of 10, 20, and 30 mm, respectively. b Profiles of holograms 1, 2, and 3 (from left to right) along the lateral and axial direction. c The simulated and measured acoustic field of the hologram 2 translated along the beam direction by 5, 10, 15, and 20 mm. d The simulated and measured acoustic field of the hologram 2 rotated by 0°, 3°, 6°, 9°, 15° and 30°. Sim simulation, Mes measurement.
