Ultrasound beam characteristics. (a) Normalized 3D pseudocolor empirical plot of ultrasound beam recorded in free water. Maximum I sppa in free water was 14.56 W/cm2 with an MI of 0.89 and 7.03 W/cm2 measured through a sectioned human temporal bone. (b) Normalized pseudocolor empirical plot of XY lateral resolution (taken at Z maximum) of ultrasound in free water. (c) X, Y, and Z normalized line plots of pressure profiles normalized to peak pressure. Dashed lines and red numbers indicate −3 dB pressure attenuation in respective axes
