Seems like the US scanner will just reflect back the interface between different tissues. Andd it won't be able to penetrate that deeply. No useful medical data that a radiologist can interpret.
It will be imaging garbage but the lay person won't know any better. They will likely have appropriate disclaimers for the medical imaging.
The money maker seems to be the whole spa experience, with the garbage US scanning as a unique draw. Like an aura reading or something.
Will be interesting to see how this turns out.
