They spent a lot of time selling the spa, and not a lot of time showing us the data.
That's because there isn't any data yet, at least not enough from real patients to be meaningful. I would love to see some of the raw imaging data they have generated though, if that's what you mean.

It's true that sometimes deeply experienced professionals are less likely to discover or accept novel methods based on new approaches or technologies. Unfortunately, in this case MJ's proposed product is being deceptively presented to appear as if it's the kind of bold new approach we all hope to see in medicine - but it's not. It's a repackaging of an existing product that's already on the market. MJ is buying the t…
Exponentially would make it computationally intractable by definition, and is the proposal suggestion that having simultaneous sensors can be used to reconstruct more information than the conventional way of using a handheld single sensor? Is that plausible?
But frankly, I'm losing interest trying to glean what someone might be thinking, when they're being so intentionally opaque while making such grandiose vague claims. The bottom line is, if they really thought this way of nerfing Butterfly's chip '9-steps back' with disadvantages, would truly unlock 12-steps forward in actual medical imaging utility, they wouldn't be launching it as a 'feature' of a vanity spa with nothing but vague 'tech visionary' puffery.

to be fair I wouldn't call people operating AI Image generators creative people. At best they're people curious about the technology itself, anybody willing to learn and do it for the sake of being creative does it themselves.
This is just complete nonsense. You really think creative people are not interested in new forms of visual expression? This as simply being ignorant of art history.

> The brain is encased in bone, so you might get some penetration but it will be very limited. Radiologist as well. Remember this is full wave inversion not pulsed wave B mode. You can get much more useful information from both high low frequency and capture transmitted waves. There is promise with this and we use it for example with MRgFUS. With advanced computational models or patient specific CT/ZTE MR aberration…
What does "more useful" mean in this context? Can you solve gas-filled bowels with the mode difference?
Ultrasonic waves can penetrate most structures in humans, including the brain. For example, with focused ultrasound (as they mentioned with MRgFUS) you can burn specific structures in the middle of the brain without any incision.
To use this for imaging, you need lots of transducers (MRgFUS typically uses 1024 for ablation, and Midjourney is proposing 358,000 for imaging) and massive advances in computational tomography capabilities. There will still likely be pockets of low confidence where there's a lot of air, like in the lungs. But with sufficient information on what's happening around those areas, you'd still have something that's medically useful.

Citation very much needed.

> You want as much data as you can get about your health as quickly and as cheaply as possible. In other words, you want a technology optimized for getting as many “megabytes per second per dollar” of information about your body. This is so far from my vision of what I want from healthcare.

My man, YOU USE THOSE bytes for that purpose exactly.

I’m a weirdo who vaguely enjoys my MRIs. I’m moderately claustrophobic, but they still don’t really bother me. And I love the warming feeling that makes me feel like I’m getting microwaved.
What warming feeling? An MRI shouldn't really make you feel warm unless they're pushing IV contrast.

The way we figure out how to catch issues before you notice them (i.e. proactively keeping you healthy) and figure out the best ways to fix them (i.e. reactively helping you get back to healthy) is by having more data from more people in more situations, so we can make those determinations. I understand some of the current fatigue around biohacking and chasing perhaps-irrelevant metrics, but takes like this surprise…
Also, we know a bunch of stuff to proactively keep us healthy but we tend not to do them very consistently when they are at odds to the normal conditions of our living - it's very easy to sit too much, neglect family and friends, eat calorie dense foods, not sleep enough, never walk 8 kilometers to get our daily bread, ingest a variety of synthetic compounds of proven bioactivity, smoke, etc. etc. etc.
As long as the pool is saying "get this thing cut out" we'll do it, but when it says, you should cut back to 30 hours of work a week and call people to hang out with more often, we'll ignore it.

I understand your point, and I might even agree to some extent. However, the issue is that this isn't presented as an opportunity to do research, but as commoditizing a clinical test that, when it isn't done for medical reasons (i.e., investigating some existing symptoms), can lead to a lot of false positives.
This is exactly why it's a bad idea. I agree that if this technology comes to fruition, it should be in every clinical and research setting as a tool for us to further our understanding. It shouldn't be a commodified test anyone can do at any time they feel like it. There are so many examples this leading to over or misdiagnosing already. I've seen patients who thought they had diabetes because they got a CGM over th…
Because the status quo is not working for a lot of folks in managing their own health, and just saying "it has to be this way" --while every other aspect of their life takes advantage of a wider range of options -- leaves them careening into MAHA style crazyness .

I read the site and it seemed pretty clear? It's a 3d, transparent, high res image of your whole body reconstructed from the wave data from a large number of high frequency ultrasound scans. But it's also a high end spa in San Francisco that softly scans your body. Then, you uh, do as you want with the data (presumably show it to your doctor, who will be perhaps bemused)?
Sometimes I cannot wrap my mind around how funny people can be and how utterly humorless HN has become with its downvoting. @dang this is valid for the community too!
