Breast ultrasound tomography problem, simulation with noisy model

The work is devoted to the problem of determining small sound speed fluctuations in glandular tissue for specific breast model [1], [2]. Our approach, proposed in [3],[4], is based on visualization of inclusions and unknown inner boundary between fat and glandular tissues and determination of sound speeds in inclusions using kinematic argument. In this work we examine stability of our algorithm with respect to a noise in the original breast sound speed model. We use Gaussian noise with different intensity.
