It works well.</p> <p>Now I want to define the initial value of each transducer to steer the focus or simulate muti foci in stead of using time delay.I want to set different complex pressure or velocity for diifferemt element.</p> <p>Can I change the settings of input signal to achieve this goal or where do I have to change?</p> <p>Thanks you!<br /> Ykx </p>
