For a recent project, I would like to construct a small-scale HIFU system to be focused onto a small sample, ideally inducing an oscillation (velocity) of around ~1000 cm/sec. However, upon researching into this topic, I've only really found information on systems used for medical applications. Does anyone have any starters on how I can go about building such a mechanism, or pointers on where to find out how? Alternatively, is there an easier/more efficient way to remotely oscillate a sample? Thank you for any feedback.
