A study of high frequency ultrasound scattering from non-nucleated biological specimens.

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

Background: Ischemic stroke is a major cause of mortality and morbidity worldwide. Various studies on the etiology of this disease are in progress. Some studies have suggested that opium abuse may is associated with increased risk of ischemic stroke. The present study aimed to analyze the frequency of opium addiction and to compare cerebrovascular ultrasound patients’ changes to non-addicts. Me...

We demonstrate that microscopic imaging is feasible in ultrasound-modulated optical tomography (UOT) of soft biological tissues, using a high-frequency focused ultrasound transducer with a 75-MHz central frequency. Our experiments in tissue mimicking phantoms show that at an imaging depth of about 2 mm, an axial resolution better than 30 microm can be achieved, whereas the lateral resolution is...
