In sizing defects, tomographic methods such as the Synthetic Aperture Focusing Technique (SAFT) can be used here the time of flight of the received ultrasonic signals plays is more important than the signal amplitude height. There are two main features of the software, a simulation module, which allows a generation of a CAD-drawing of the component, to place and automatically scan the search unit, to introduce artificial flaws, to trace the reflected and mode-converted waves and to image using the principles of SAFT, which allows the generation of 2- and/or 3-dimensional reconstructions on plates, piping, or nozzle-to-shell configurations. In the case of a complex component geometry, the CAD-module can generate the component contour based on measured data and perform data reconstruction by using the actual shape of the real component.
