   hello. i wanted to ask if anyone here can tell me whether it is possible to model human body fat in k wave. also what will be the value of medium.alpha_coeff, medium.alpha_power, medium.BonA for fat if we want to design the medium as body fat in ultrasound transducer example in k wave. help needed asap.

   Also I want to use half of transducer elements for one frequency and half of transducer elements for other frequency. Is there any way that i can achieve results by making only one transducer object?

   Hi humda,

   There are several references for the properties in fat. As an example, the data from Szabo, T. L. (2004) "Diagnostic ultrasound imaging: inside out" has the following values:

   sound_speed = 1430;
   density = 928;
   BonA = 10.3;
   alpha_power = 1;
   alpha_coeff = 0.6;

   Using the kWaveTransducer class, it is only possible to have one driving signal. However, you could create your source manually using the time varying source inputs.

   Brad.
