Harmonic Elastography Through Time-of-Flight Calculations

This work addresses the IUS challenge focused on assessing the accuracy of various methods in providing elastography images of soft tissue using shear wave elastography (SWE) data, specifically from harmonic excitation. The challenge is not necessarily aimed at developing new methodologies but applying existing (or new) methodologies to assess their accuracy. In this spirit, we illustrate that simple time-of-flight calculations can provide useful first-order-approximate reconstruction of the underlying structure.
