Ultrasound probe

I would like to design a simple (as possible) ultrasound probe and use an arduino and processing to image the result. I am having trouble finding info, especially usable transducers.

Does anyone have any pointers?

Thank you!

Define “ultrasound”.
Define “probe”.
Define “image”.

I’m not surprised you’re having trouble.

I am having trouble finding info

I got almost 6,000,000 results when I plugged "ultrasonic probe" into google search. Shirley there must be something of use in there.
