However, in most conventional applications of clinical ultrasonic scanners only the peak amplitude
echogenicity is used to create the image. Moreover, signal envelope detection destroys
potentially useful information about frequency dependence of acoustic properties of tissue
comprised in RF backscattered echoes. We have explored the possibility of developing the
method of imaging the distribution of the acoustic attenuation in tissue. We expect that the
method will help in localization of the pathological states of tissue including tumors and
diffuse liver diseases. The spatial resolution and precision of the method are crucial for
medical diagnosis, hence the synthetic aperture technique was applied for ultrasonic data
collection. The final goal of the presented project is to develop reliable diagnostic tool, which
could be implemented in standard USG systems, as the new visualization mode.
