https://doi.org/10.1007/978-3-476-98932-1Various correction methods have been proposed to obtain better images for these cases.-.. In order to test the applicability and limits of the correction methods, it is important to have an accurate and efficient computational model describing the propagation through these distorting tissue layers.

Reconstructing images of such objects from measured transmit or scatter fields provides a considerable challenge and the reconstruction approach that is most suitable may depend on which of these processes dominate. In order to gain a better understandi

For this purpose special comparison and measuring methods for the recognition and quantitative embracement of the propagation phenomena in inhomogeneous media were developed. Propagation phenomena appear in many cases as special attenuation issues or as characteristic freque

Due to the large number of measurements required, it is convenient to restrict data acquisition to a subset of points, usually acquired in a plane. This measurement set, combined with some appropriate theory (co

Using a combination of the finite element method and Huygens’ principle. and considering attenuation with a perturbation approach. the propagation in a homogeneous medium can be computed in a satisfactory way. However, the right way to predict pulse propagation through inhomogeneities is
