There were a lot of people who declared very loudly last week during the Midjourney discourse that this was an impossible use of ultrasound.
- Aurornis 3mo agoThe 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.
- NitpickLawyer 3mo agoThe 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.
- fragmede 3mo agoExactly. 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.
- dwroberts 3mo agoIs Aleph an established entity with a track record that should lead us to trust this at face value? I couldn’t find any info on them and the site seems new
- dwroberts 3mo agoOof did a bit more digging: https://x.com/_marleyx/status/2070260772635312598 https://x.com/_marleyx/status/2070260772635312598 > None of us were ultrasound scientists before this. We worked backwards from a desire for brain interfaces and taught ourselves physics, ultrasound, electromagnetism. Not to say it’s not interesting or neat, but the Silicon Valley approach to solving medical issues doesn’t have a good track record, let’s put it that way
- xboxnolifes 3mo agoWhat was impossible is the scale they claim to be targetting.
- haldujai 3mo agoHalf baked images? No one said that is impossible. I am skeptical of any brain ultrasound claim that doesn’t use skull correction which requires a CT scan. Very large chunks of vasculature and major arteries are missing in the images they provided. Just because it’s pretty and colorful it doesn’t mean it’s useful. Perhaps it will one day, but this doesn’t prove much so far. There are several physical challenges to using ultrasound.
