Abstract

The simultaneous and/or quantitative recovery of optical absorption and scattering coefficients in ultrasound modulated optical tomography requires the use of a model-based inversion procedure. In this work we employ a linearised forward model as part of a non-linear image reconstruction process, recovering parameters with an error of less than ±3% from simulated measurements with 1% Gaussian noise and initial conditions differing by 10% from the actual background.
