So, on the one hand, this is interesting! Reducing radiation from CT scans is a noble cause on its own. If on top of that it could make tomography cheaper and easier, you could imagine getting earlier detection of aneurisms, fibrosis, cirrhosis, thrombosis, stenosis, even plausibly cancerous masses (along with plenty of over-detection). On the other hand, nothing here substantiates this promise. We've got a video ren…

I'm not putting my head under. How do we know this won't cause aneurysms? Damage eyes and ears? Getting a medical device approved takes time because of concerns like this.

From my understanding of the post, the waves that are created are smaller than light waves, and there's no evidence that light waves, sound waves or sub-sonic waves have any aneurysm-causing effects.

(I researched more and found in the video a value) The waves are 50 nanometres, and this is basically the equivalent of having a full body ultrasound. We've been doing baby ultrasounds for decades with no ill effects, so I can't imagine this being different

The spa is brilliant. Think of corporate rec days that also cut insurance costs. Good lord, its like you're new to hypercapitalism :)

I think a lot of medical diagnosis could be solved with mass data collection if it was cheap enough. Right now, blood draws are somewhat routinely done because they provide a lot of human-interpretable indicators from a small number of values, and there is some evidence that e.g. "dogs can smell cancer" etc. (i.e. some diseases cause detectable odors).

This is really interesting! And perhaps surprisingly doesn't trigger any immediate major technical red flags (as someone who has worked with MRI and phased array beamforming), as many HN HW articles do.

My only criticism from the tech video would be that they spend some time lauding the nanometer deflection sensitivity, which might lead some to believe that's indicative of the image resolution. It's not, and it's somewhat of a distraction -- that's just giving us amplitude information, which is comparatively less important than correlated time/phase across the 100k sensors. They do later on state ~mm resolution, which is still great!

Doppler and motion blur may be an issue (e.g. heart beating), as one slice requires a full ring of sequential exposures. But still way faster than MRI, so probably fine.

On a lighter note, it could seriously change the meaning of get FUCT (Full body Ultrasound Computational Tomography)!

I have libertarian enough tendencies to think that if a person wants to self-operate, or pay for an operation that doctors are telling them is not justified given the evidence, then they should have right to do it.

The solution to imperfect evi…

The risk estimation is why people aren’t recommended to get scans! There are studies on ‘VIPs’ who get ‘executive MRIs’ and wind up getting treated for things that would never have justified intervention.

Isn't the way we decide what justifies intervention by comparing observational data, action and outcomes? Currently our observations are limited by many things including the cost and side effects. More frequent or better observations will improve the assessment of what justifies interventions.

Rather than dealing with the issue—hypochondriacs or whatever—you prefer to remove the option for the non-hypochondriacs? The fact that doctors like your wife think that people who are concerned about their health and want more information is a problem tells me everything I need to know about your (and her) worldview. You've dressed it up as being pragmatic, but the reality is that you're arguing for censorship and a…

>that people who are concerned about their health and want more information is a problem It is a problem because there's evidence based standards for when examinations are indicated and prolong or improve a person's life. You being extremely concerned doesn't move that needle and subjecting you to tests simply because you're anxious is blatantly unethical and harmful to your psychological wellbeing. And nope this isn…

That's definitely an important point to consider, in fact something I think everyone in these conversations should be cognizant of, and also why it makes me believe the actual conversation should move to whether the device improves false positives/negatives rates or not (or at least has a chance to), which then might warrant wider access/use.

what's the novelty? mixing healthcare together with a spa is an idea older than Christ. USCT is decades old. Their butterfly chips might be cool, but it's not like the article says anything about that. There's only one other comment in the whole thread that even mentions it.

I find using tens of thousands of ultrasonic chips, submerged underwater to provide you a radiation free full body scan, all while processing a petabyte of data per scan a pretty ambitious and cool project. I hope they make it work.

1 petabyte per 60 second scans implies a kind of comical data rate to storage, even at RAM speeds that’s implausible. Imagine we need to write these to hard drives, they happily sustain 150Mb/s on the high end, which would imply you’d need 115,000 hard drives to absorb that amount of writes. Even with top end NVMe drives you’d need a thousand of them writing simultaneously.

Are you joking? 人間ドック is absolutely more than a "health checkup". Maybe do some reading: https://medical.kameda.com/general/en/ningendock/what/ > The Ningen Dock is a comprehensive health checkup system that includes a battery of tests, including blood tests, chest X-rays, and ultrasound scans, among others as well as advanced diagnostic tests as Magnetic Resonance Imaging (MRI), Computerized Tomography (CT) or Endos…

That is not the same as the annual mandatory health check. Maybe your employer pays for you to get a more comprehensive checkup by default and you're unaware of this? But the ones vast majority of population here gets do not include MRI or CT or Endoscopy. And, _even then_; specific checkups when you're looking for _specific things_ are still very different things than a full-body MRIs.

Only if you let them. The false positive thing is a nonissue that only arises from assuming you would respond to information a certain way.

Yeah, that's not just 'cart before the horse', it's more like cart before the wheel. They make a bunch of extraordinary claims yet offer zero evidence, info or even a plausible hypothesis on how those claims might be possible at the scale, timeframe (2027) and unit economics implied. Thank goodness they really thought through the accent lighting for a calming user experience though. Otherwise, I might have been concerned they're not serious.
