Table 1.

Acoustomechanical and thermal parameters used for simulations. For the sake of simplicity, the same properties were assigned to brain and periosteal tissue. Bone density was determined from CT data, the speed of sound c(ρ), and attenaution α(ρ) in bone were evaluated using the relations established by Pichardo et al. (2011). Soft tissue acoustic properties were from (Duck, 1990). Acoustic propagation in air was neglected and the speed of sound in air was set to 0. The other properties are listed and referenced in (Pulkkinen et al., 2011).
