Temperature and frequency dependence of ultrasonic attenuation in selected tissues

Ultrasonic attenuation over the frequency range of 1.5–10 MHz has been measured as a function of temperature for porcine liver, backfat, kidney and spleen as well as for a single specimen of human liver. The attenuation in these excised specimens increases nearly linearly with frequency. Over the te...

More Information
Summary:Ultrasonic attenuation over the frequency range of 1.5–10 MHz has been measured as a function of temperature for porcine liver, backfat, kidney and spleen as well as for a single specimen of human liver. The attenuation in these excised specimens increases nearly linearly with frequency. Over the temperature range of approximately 4°–37°C the attenuation decreases with increasing temperature for most soft tissue studied.
