I’m attempting to make a model for medical professionals to practice ultrasound guided procedures. What substances or materials would be adequate to project a picture similar to human tissue? I have a few ideas but want to pick your brains. Thank you
There is a substance called ballistic gel that is used by bullet manufacturers to shoot bullets into, to test their behavior when passing through flesh. Since it is designed to mimic the bodies of large mammals, perhaps it would work for your purposes.
it is sold as a dry powder to which water is added, after which it sets up like very stiff jell-o. By adding lumps of stuff like barium sulfate to it, you can vary its density locally and thereby get ultrasound reflections off it.
