Characteristics of tissue equivalent gels intended for passive test procedures of ultrasonic scanner performance

The ultrasonic qualities of hydrophobic gels with various cross-linked internal structures were investigated. It was found that thermally and mechanically stable gels with ultrasonic properties resembling many mammalian tissues can be produced and may be useful as a reference among hospital clinics in quality assurance tests and training of personnel on diagnostic ultrasound scanners. This paper summarizes some of the results of these studies.
