This is complete nonsense. Ultrasound can’t effectively penetrate the skull. The entire thing (and Midjourney’s) is vibed-up nonsense.

The only reason this even exists as a brainfart and hasn’t been immediately laughed out of VC funding is because other imaging modalities require either ionising radiation (illegal to produce without source licences) or an enormous magnet (would be wildly unsafe in the hands of what appear to be circus clowns).

Geoffrey Hinton was hilariously wrong 10 years ago about replacing radiologists, and this is just embarrassing. Maybe try fixing US healthcare funding instead if you want cheaper scans.

There is a line of research right now using ultrasound as a king of treatment for mental disorders, similar to TMS approaches. It's not that the sound can't get there, it's whether you can get information back from it.

Ultrasound can penetrate the skull, esp if through a thin part of the skull (like the temporal bone, which going from the graphic on the website is exactly where they are targeting these waves) and with targeted frequencies.

You are misinformed.

I am a consultant radiologist. Tell that to my 6-month old infants who require MRI with GA because their fontanelles are closed. Transtemporal can give you a poorly resolved image of the 3rd ventricle at a pinch.

“Targeted frequencies” - righto.

[insane_dreamer]

It definitely can penetrate the skull, and transcranial focused ultrasound has been around for a few years now with plenty of studies.

So that development isn't new; what's new is to use it broadly for imaging instead of for highly targeted stimulation.

[tokyovigilante]

Not to the level of clarity and detail presented here, which is not possible from a basic acoustics physics premise. The “technical blog” is marketing fluff.

[insane_dreamer]

that's why I said: "what's new is to use it broadly for imaging"

[tokyovigilante]

That’s the made up part though.

[insane_dreamer]

right, that may indeed be so
