Are y’all familiar with what Openwater has been up to? my hunch is that it wouldn’t give high enough resolution for the things intended here, but I figured it was worth mentioning: it works by doing holographic descattering in infrared through the skull, and apparently has MRI-level resolution. I have wondered if combining it with AI is possible, or if they’re already relying on AI to get it to work at all. The summary that first introduced me to it was their ted talk—though there are also other discussions with them on youtube. I didn’t find a text document which goes into a ton of detail about their tech but somewhat redundant with the ted talk might be one of the things on their “in the press” list, eg this article.
I carefully read all the openwater information and patents during a brief period where I was doing work in a similar technical area (brain imaging via simultaneous use of ultrasound + infrared). …But that was like 2017-2018, and I don’t remember all the details, and anyway they may well have pivoted since then. But anyway, people can hit me up if they’re trying to figure out what exactly Openwater is hinting at in their vague press-friendly descriptions, I’m happy to chat and share hot-takes / help brainstorm.
I don’t think they’re aspiring to measure anything that you can’t already measure with MRI, or else they would have bragged about it on their product page or elsewhere, right? Of course, MRI is super expensive and inconvenient, so what they’re doing is still potentially cool & exciting, even if it doesn’t enable new measurements that were previously impossible at any price. But in the context of this post … if I imagine cheap and ubiquitous fMRI (or EEG, ultrasound, etc.), it doesn’t seem relevant, i.e. I don’t think it would make uploading any easier, at least the way I see things.
