Modelling high frequency acoustic backscatter response from nonnucleated biological specimens

摘要: A study was conducted to investigate the high frequency acoustic backscatter response from non-nucleated biological specimens. The used sea urchin oocytes prepare sparse suspension in artificial seawater at room temperature. VisualSonics VS40B ultrasound imaging devices during for data acquisition with transducers. also carried out a visual inspection remove abnormal patterns due presence of more oocyte. An absence detectable shear waves propagation inside oocyte observed sharp resonance peaks. found that behave like fluid scatters ultrasonic frequencies. can be sphere scattering models.
