Entwicklung einer gewebeäquivalenten Kunststoffvorlaufstrecke für die sonographische Diagnostik hautnaher Bereiche

Abstract
A very soft and homogeneous plastic material has been developed from polyvinyl chloride with acoustic properties similar to those of human tissue. During an evaluation period of nine months, the material has proved excellent for the sonographic investigation of subcutaneous tissue, even at high frequencies. Significant advantages of the new material as compared with previously available substances depend on its stability, low sound attenuation and absence of reverberations. In order to achieve these desirable properties, twenty plasticisers of different type and concentration were used and the resulting compounds examined for their acoustic properties.
