   Hi, there!

   I want to caluculate 3D nonlinear field of the phased array.I use the Simulating Ultrasound Beam Patterns Example. It works well.

   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.

   Can I change the settings of input signal to achieve this goal or where do I have to change?

   Thanks you!

   Hi Ykx,

   If you are using an object of the kWaveTransducer class then you can only use a single driving signal for the whole transducer.

   If you want to do something more complex, you will need to setup the simulation using pressure and velocity sources (see the time varying source problems in the k-Wave help browser).

   Brad.
