Simulated impact of steering angle on pressure attenuation and focal shift. −6 dB focal regions of simulated focused transmits with varying steering angles through the (a) NHP skull and (b) human skull. Asterisk denotes center of the focus in free field, while circle denotes center of the focus after transcranial transmission. dB scale on color bar is self-normalized for each pressure plot. Steering angle dependent focal shift and attenuation through the NHP skull (c-d) and human skull fragment (e-f). Statistical significance determined by one-way ANOVA with post-hoc Tukey’s multiple comparisons test where, **p<0.01, ***p<0.001. ****p<0.0001, for n=6 simulation trials.
