| Popis: |
In vivo ultrasonic attenuation was estimated for extracranial soft tissues of two Tursiops truncatus and one Delphinapterus leucas. Backscatter data were non-invasively collected as part of routine health-based ultrasound examinations using a transducer operating in the 2.0–3.5 MHz frequency range. Data sets collected over the proximal mandible and temporal regions were processed to yield estimates of attenuation using a reference tissue phantom whose properties had been independently determined. The estimated attenuations were at the low end of the range of reported values for in vitro mammalian fatty and connective tissues. |
