Description

In recent years ultrasonic imaging procedures have been developed to quantify defects [1,2,3,4] for application in QNDE or medical imaging. The demands for these purposes are high resolution images, true recovering of the scattering geometry and fast computer processing. But most of the published algorithms require certain assumptions as: plane wave excitation, measurements in the farfield of the scatterer or, which is a very serious restriction, scalar wave propagation.
