This can also be used for prostate, it's nothing new. But you cannot use this anywhere where the ultrasound would be blocked by other organs. Fun fact: using this ultrasound for prostate cancer treatment reduces the risk of erectile disfunction

Can’t the surgery be then with a small probe just to get the ultra sound tip near the cancer? I don’t know the size of the ultrasound tip but seems to me it can be smaller then a hand or tweezers.

  Often constructive and destructive interference of waves can be used to focus the ultrasound through tissue without any incisions at all. Kidney stones are sometimes broken up this way.

> 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.

  Urinary and erectile function are a major issue with partial and radical prostatectomy. These ultrasound treatments are showing significant improvements in both areas. This technology is also now used to treat non-cancerous prostate enlargement (BPH).

    - wlaw15 1y ago
      True, but currently prostatectomy is the most common intervention and second is radiotherapy which as mentioned in a comment above is a very expensive alternative with known side effects. Histotripsy is early in its clinical life but I wouldn't say untested.

        I’m not sure why we’re plugging a brand new entity when PAE is already in guidelines. People who aren’t in medicine are very susceptible to advertising - this is why I’m writing so stridently

The article mentions that this is a different type of ultrasound treatment than the one that has been in use for prostate cancer treatment for some time.

>But you cannot use this anywhere where the ultrasound would be blocked by other organs. 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.

  We were privy to a lab that accidentally cooked mice with gold nanoparticles in the late 90s with multiple IR lasers. After they figured the power side, it turns out that gold nanoparticles are wildly cytotoxic on a number of axes.

  IN fact, they do this today to break up kidney stones. Multiple beams.

  How is it more trivial with sound? Sound is just a wave just like ultrasound. In fact, ultrasound has the word sound in it making it sound. So your conclusion is not sound.

    Reread, and you'll realize it means more trivial than RF.
    - dylan604 1y ago
      Ugh, yes. Not sure how the wires got crossed like that. However, sound is just a wave while RF is also waves even if at higher frequencies. Just as ultrasound is higher frequency that audible sound (which I guess is how "sound" was being used). If you continue increasing the frequencies past the RF range you will eventually get into light. You just gotta catch the right wave
