Every few years one of these ultrasound companies comes around and promising to revolutionize medical imaging and nothing ever comes of it. Anyone remember https://www.openwater.health? The same ideas are in a perpetual state of being reinvented and part of me thinks its just a hustle for the MIT Media Lab/Stanford Imaging grads to give them something to do.

The tell is "super resolution", "brain computer interface" and "mixed modality" -- adding some contrast agent here, or maybe an IR light source.

It turns out the nyquist limit, diffraction and physics are real things.

It doesn't work until it does.

The same thing has been said about robotics, AI, space travel, etc. etc.

I'm not saying this is the way, and I have significant questions of understanding thought based on reading brain activity, but I wouldn't put down the entire ultrasound field.

It doesn't work unless it does.

Until implies we're just waiting. Unless implies actual evidence, and - in medical procedures - some guarantee of safety.

SF6 plus ultrasound is used to open the blood brain barrier. So if you're pumping a lot of ultrasound into a brain and using a lot of SF6, there are already risks.

but technology is getting better all the time what doesn't work because they only have one Tesla, well shit, let's try it with 100.

It isn't a matter of technology. It's physics and math. These things are already very well understood, just not by investors. And that creates room for the hustle.
