Efficient analysis of high-dimensional ultrasound data in non-destructive testing
Joint BMBF research project
ZeMat1: Reconstruction of 3D defect characteristics in welds
In this project, a new efficient reconstruction method will be developed that is specially designed for weld testing with ultrasonic
phased-array probes. We apply the total focussing method (TFM) which has, in contrast to the typically used Time-of-Flight-Diffraction method (ToFD),
a high data redundancy. The obtained data shall be employed to improve the denoising of the given b-scans. Therefor, a suitable function system for b-scan
representation is needed, e.g. real valued Gabor functions. The problem becomes even more challenging considering more detailed models
incorporating influences of sound absorption, refraction, defraction and interferences.
