A transducer array design for acoustic frozen waves generation with a kerf optimization for biomedical applications

In this paper, a design of transducer array to implement Biomedical Applications by Acoustics Frozen Waves, such as diathermy, hyperthermia, tissue ablation tissue, is presented. The example shows a method to obtain an optimal space between rings (kerf) for each F_z, based on minimization of RMSE. The results of kerf VS RMSE, for our synthesizing functions F_z, show that the minimum kerf is the best for a minor RMSE. However, the optimum kerf is dependent of field pattern F_z, over z axis. Finally, we proposed the inspection of other parameters such as the position of each ring, the harmonic distortion of the driving signals, the variations on the amplitude and phase of the driving signals, and others, are proposed.
