There were a lot of people who declared very loudly last week during the Midjourney discourse that this was an impossible use of ultrasound.

The damage done by Elizabeth Holmes at Theranos goes way further than just that company. There is a lot of distrust now in anything tech that touches on medical devices. Some of it is for good measure, some of it will prevent really cool stuff from happening.
Exactly. The concept itself; a machine that can do a bunch of tests from a whole lot less blood would be amazing but anyone who wants to do this now is automatically "oh so like Theranos" and then not gonna give you money to do this PhD or post doc and do you figure out a way to do this? You can't raise money because everyone's gonna be thinking of Theranos.
The Midjourney scanners don’t do the same thing that this is using. See how blurry the first image on the page is? That’s what you get from ultrasound through bone like the skull.

They used a trick to inject sparse bubbles into the patient and let them flow through the brain, then looked for the perturbations caused by those sparse bubbles.

The Midjourney scanners aren’t injecting this bubble contrast agent into everyone’s veins.

This scanner doesn't inject bubble contrast either. A nurse does it. Obviously a nurse could do that when you use the Midjourney scanner too...
Absolutely, but it was claims about ultrasound in general
