   Hi,

   I need to model human skin mimicking medium. Therefore, I want to make the simulated model more complex. My questions about this are:

   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?

   2) How do I add noise? Am I able to add noise for a particular grid point(s)/a region in the medium?

   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:

   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?

   Finally, can you provide simulated complex heterogeneous medium data with all parameters are defined?

   1) You could use a digital phantom, for example, this excellent breast phantom from Mark Anastasio's group.

   2) Take a look at the "Simulating B-mode Ultrasound Images Example"

   3) Take a look at the "Defining An Ultrasound Transducer Example"

   (The examples are accessible in the MATLAB help browser).
