Abstract :
High sidelobe levels of ultrasound beams can generally be reduced by apodizing the sound emitting aperture. The integrated sidelobe energy could be a criterion for the optimization of such an apodization. Thus, we developed an algorithm, which generates an apodization that minimizes the sidelobe energy for a given width of the ultrasound beam. The performance of the algorithm was evaluated on simulated ultrasound fields.
