Abstract
In this paper we present a simple algorithm for determining the mass density of an elastic inclusion from the knowledge of how the inclusion scatters known incident elastic waves. The reconstructions are obtained with the Contrast Source Inversion method (CSI), extended with a multiplicative regularization and using transmission and reflection measurements.
