%X Distorted Born iterative method (DBIM) using multi-frequency information has been studied and applied in ultrasound tomography. However, the use of different frequencies in different iterations in the DBIM method is not used consistently.   The value of the  frequency hopping step is often chosen   depending on the simulation builder or experimenter. Based on the multi-frequency combination technique,  this paper  suggests an  effective multi-frequency combination procedure to improve the quality of reconstructing  ultrasound images using fundamental tone and overtones (FTaOT). The numerical simulation results show that the normalized error  of the suggested  scheme  is  decrease  by 45%  in comparison with  the dual-frequency method. Other multi-frequency combination scenarios are also simulated to demonstrate the feasibility of the proposed method.
