Blood mimicking

An important part in the design of a CW doppler is the phantom: the blood mimic. The two following files permit to create a phantom:

hello I am so interested in your proyect. I have a very similar proyect to yours, but instead of sensing human blood I have to Know if an embryo of a CHICK inside the egg is alive. I am trying with IR but I think that with ultrasound will be better, With th beat of the samall animal,Will I be able to sense his heart??And if I use ultrasounds of 40khz, will be enough only for seeing changes in the heart of the embryo(i only want to know if it is alive)Thank you very much
