[Basic research on impediography].
Impediography, a method for ultrasonic tissue characterisation, is theoretically and exerpimentally investigated. After a short description of the mathematical formalism ("Inverse Scattering Problem"), digital processing of broadband ultrasonic signals and measuring problems are discussed. The obtained results are completed by measurements on tissue structures in vitro. The paper shows the limits of the application of impediography if inhomogenous tissue structures are present.
