Hi Bradley,
I recently attempted to use a kWaveArray object for simulating a 2D planar array. The question is how can I define arbitrarily a focal point of the array? Can I use the focus function of the k-Wave toolbox to produce delayed signals for each element？
Thank you in advance!
Hi Xiaopeng,
No, you can't use the focus function in k-Wave. This sets an offset time signal for every grid point. Instead, you will need to define your own input signals for each physical element in the array (e.g., using the distance between the element and the desired focus), and then assign these as shown in ex01_simple_example_kWaveArray_source.
Brad.
