Autocalibration method for guided wave tomography with undersampled data

This paper presents a baseline-free quantitative method for the imaging of corrosion flaws present in thin plates with under-sampled data. This method is based on the Hybrid Algorithm for Robust Breast Ultrasound Tomography (HARBUT) which is itself inherently baseline-free. However, in order to ensu...
