ULTRASOUND PHYSICS Name Institution a) Calculate the Acoustic impedance of subcutaneous tissue‚ muscle and bone. Assume subcutaneous tissue has a density of 1060kg/m3 (Hedrick 2003)‚ muscle has a density of 1104kg/m3 (Madjor 2008) and bone has a density of 5065kg/m3 (Hedrick 2003). Give your answer in Mrayls. Please use speed of sound as 1540m/s for tissue‚ muscle and bone In ultrasound‚ Acoustic impedance (Z) is the quantity of measurement of resistance to sound when passing through a medium

Ultrasound Quick Project Ultrasounds are sound waves with frequency beyond the human limits‚ therefore humans are unable to hear them. It even travels at exactly the same speed as sound in any medium. Humans can hear sound within the frequency range of about 20 to 20‚000 Hz‚ so any sound above 20 kHz is ultrasound. Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves and their echoes. The technique is similar to the echolocation used by bats‚ whales

Contrast-Enhanced Ultrasound Introduction: Ultrasound is a non-ionizing‚ medical imaging modality that uses high-frequency sound waves and their echoes to produce images of organs and their movement in real time. A major limitation of ultrasound imaging is the often poor definition of the produced image. This poor image definition is attributed to ultrasound frequency in which there is a trade-off between spatial resolution and attenuation. This trade-off has been remedied by the introduction of
