Abstract
The concept of computerized tomography (CT) is not only applicable to X-rays, but also to other kinds of rays, for example to ultrasound /1-8/ and to microwaves /10/. These non-ionizing waves are known to be safe for medical diagnostic purposes. Ultrasound computerized tomography (USCT) is possible in different modes: in the transmission-mode acoustic absorption as well as acoustic velocity can be used to reconstruct as a cross-sectional distribution. Furthermore, parameters which characterize the dependence on frequency of these quantities can be displayed. In the reflectionmode the distribution of reflectivity can be reconstructed using the CT-concept /4-6/. Additionally, the measurement of diffracted signals allows tomographic imaging of inhomogeneous media /8/.
