摘要: The high frequency backscatter from cells with a nucleus to cell volume ratio of 0.50 cannot be adequately modeled as homogeneous sphere. It was hypothesized that the cytoplasm such is fluid nature. This work attempts model ultrasound ( 10 – 62 MHz ) some non-nucleated biological specimens. done by measuring response individual sea urchin oocytes and comparing it theoretical predictions in both time domains. A good agreement found between experimental results suggesting are
