First‐arrival traveltime sound speed inversion with a priori information

Purpose: A first‐arrival travel‐time sound speed algorithm presented by Tarantola [Inverse Problem Theory and Methods for Model Parameter Estimation (SIAM, Philadelphia, PA, 2005)] is adapted to the medical ultrasonics setting. Through specification of a covariance matrix for the object model, the a...
