Abstract :
This work is devoted to the medical ultrasound imaging problem. We present some
results of numerical modeling, using Reverse Time Migration procedure. In the numerical
experiment we use acoustical model that simulates cross-section of breast containing fat,
glandular tissue and weak inclusions with a radius from 0.8mm. It is impossible to determine
these inclusions on the image obtained after a standard procedure RTM with a constant speed
of sound. We use an approach based on a modified version of RTM to determine unknown
boundary separating fat and glandular tissue and weak inclusion. The final image contains
all the inhomogeneities and close inclusions are separated at that.
