Guided wave tomography uses the dispersive nature of Lamb waves to enable a map of thickness to be obtained from a map of wave velocity. Iterative HARBUT, the Hybrid Algorithm for Robust Breast Ultrasound Tomography has been introduced for this problem, and here it is demonstrated to accurately converge in the presence of artificial noise with a signal to noise ratio of 6dB. The method is shown to be robust with experimental data too. The issue of the more realistic array configuration of a pair of parallel ultrasonic arrays is also considered. VISCIT (the Virtual Image Space Component Iterative Technique) was introduced to solve this, leading to images with significantly reduced artefacts and more accurate contrast reconstructions.
