In the introduction of Therapeutic Focused Ultrasound from Sim4Life website, it explains that 'Sim4Life allows to compensate for the impact of skull induced aberration and focus shifting and even enables considering the inhomogeneous nature of the skull bone based on computed tomography (CT) image data. The results indicate the possibility of considerably extending the envelope of treatable regions in the head'.
When do the acoustic simulation, how to compare the effect of homogeneous and heterogeneous of the skull?
When assign the property of the skull, there is no optional selection for inhomogeneous of attenuation, velocity, and density.
