The multi-mode plane wave imaging in the Fourier domain: Theory and applications to fast ultrasound imaging of cracks
Abstract The Total Focusing Method (TFM) was generalized about ten years ago to form
images with complex ultrasound paths involving reflections and mode conversions at the
interfaces of a testing sample. The resulting multi-mode imaging allows to fully image the
face of a crack-type defect. More recently, the Plane Wave Imaging (PWI) was revisited to
perform multi-mode reconstructions with a small number of transmissions compared to the
TFM. In order to further accelerate the imaging process, we propose here to combine plane …
