Watching Hank Green's YouTube video where he found out that his cloudy pee was cancer leaving his body, he was surprised that doctors don't tell you to expect it. It can be such a morale boost.
Fun fact: using this ultrasound for prostate cancer treatment reduces the risk of erectile disfunction
I’m not aware of strong evidence in this area (not saying you’re incorrect).
For the liver indications, several elite radiology departments have had very poor outcomes with their patients, despite the strong public data. I would not, with my own prostate, try a new technology until at least a decade out, at least.
And a review: https://pubmed.ncbi.nlm.nih.gov/36686753/
Yes you can. If you had an array of ultrasonic transducers around the body you could have each of them in phase targeting a single spot. Beamforming is a thing we've been doing for years with RF. It's even more trivial with sound.

Apparently, only some tumors have a distinct and unique shape / size. The “trick” is to calibrate the resonance exactly to the size of the cancer cell. So that resonance would “hurt” only that kind of shape / size cell. Which was much harder to do than it sounds. Sadly not all cancer cells are unique and not that “easily” distinguishable by size
But I am not in the medical field and just repeating what I’ve read.
Well said. And it's either terrible or expensive (and sometimes also terrible as well).
Proton therapy for instance is amazing at targeting hard to reach tumors like those in the eye, but costs close to fix figures as it requires a team of people to design the treatment.
For comparison, a liver histotripsy costs $17.5k:

Not a bad deal for a non-invasive life-saving surgery.
