Abstract :
A simulation method for calculating the scattered field from a small, vibrating breast tumor is given. The Volume Equivalence Principle together with subcell type finite difference time domain formulation is used for obtaining the scattered field from the tumor. The Doppler component of the scattered field is calculated using the simulation results for the undisplaced and the displaced positions of the tumor. The method is validated by comparing the results obtained on a sample problem with the results of a semi-analytical analysis.
