Abstract
Present medical ultrasound systems are based on energy detection methods and therefore only utilize echo intensity information. However, phase, as well as spectral information, is recorded by the transducer, which is a pressure sensitive device, but is not utilized in present display or measurement schemes. This additional information may be of diagnostic significance since the interaction between sound and tissue is exceedingly complex, since many types of tissue can be categorized in terms of their acoustical properties, and since changes in tissue acoustical properties can be correlated with specific pathological states. Thus, in principle, in vivo techniques could be devised which would extract and separate the medically significant features of the ultrasound interactions with tissue and would display ultrasonic tissue signatures appropriate for a differential diagnosis.
