Therefore, I want to make the simulated model more complex. My questions about this are:</p> <p>1) What features k-wave provides to make the simulation more complex? For example human skin with noise and irregularly shaped vasculature etc.? What would be your suggestion for such a case?</p> <p>2) How do I add noise? Am I able to add noise for a particular grid point(s)/a region in the medium?</p> <p>On the other hand, I need to define certain properties for transducers. I use a line transducer which is located on the top of the medium. My questions regarding this point are:</p> <p>3) How can I set/define central frequency, maximum supported frequency, element pitch, directivity, and bandwidth of the transducer? Or what parameters do I need to arrange to change these parameters?</p> <p>Finally, can you provide simulated complex heterogeneous medium data with all parameters are defined? </p>
