Ultrasonic transmission measurements show that the ultrasound beam undergoes significant attenuation while propagating through the skull sample with values ranging from −12.6±1.33 dB. Simulations results indicate that scattering and mode conversion are responsible for the majority of the total acoustic attenuation (−11.2 dB). Absorption of the skull at 1 MHz was determined to be 2 dB/cm for the compression...
