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…

I can easily and cheaply generate nore megabytes per second per dollar by oversampling a heart rate monitor at hundreds of megahertz. Hell, why not hook up a second channel to the same signal and record it twice for double the megabytes? Do you see the problem here? "yeah, but nobody's doing that" Well, then it certainly is odd of them to frame it tgat way, isn't it?

This is a bit of a contrived example. The “megabytes per second per dollar” is clearly in reference to their scanner technology that the say generates terabytes worth of data, with the goal of a scan taking around 60 seconds. So I’m confused about exactly what your point is?

That’s a lot of data really fast, so if you want this 3D scan of your body, yes, you do want as much data as fast as possible. 60 seconds sounds great compared to an MRI that’s going to take 15 minutes minimum & up to an hour or more.

If you don’t want then scan then carry on as usual.

Exactly - I had switched to a one meal per day setup and have been mostly following it for a few years. Then after a routine “heart health” check all my indicators were super out of whack - the doctors thought I was on my deathbed - but I am perfectly happy pain free, in shape, physically active person… Then _i myself_ had to dig into all these tests and figure out that they were measuring the wrong thing - since the…

Sorry to branch out: How does this one meal per day work for you? There is recommended calories for a person, do you have to follow it somehow to make sure you have enough energy and exercise?

I just eat double portion at dinner, and then nibble on snacks before bed - I haven’t had breakfast in decades, then since I moved to India, with the carby nature of the food it was hard to stay in shape with 2 meals, so I decided to try and skip the lunch too. With fun work it is actually quite easy, and babysitting 4 claudes and helping out colleagues is very entertaining.

Now I either do gym before dinner (heavy exercise) or social dance after.

I’ve been given a lot of advice how I “should” be structuring it - like “don’t eat too much before bed” or “never eat before exercise” … but I haven’t had any issues with what I’m doing so far (~2 years)

Imaging is not preventive care. Exercise is. Good food without chemicals is. Good sleep is.unfortunately these important parts cannot easily be monetized to provide stock options to the insiders/

"when you're looking for things, you find them" - my physician explaining excessive reliance on diagnostic imaging

Counterpoint: When you're not looking for things, you don't find them.

Which is why the current US administration is destroying any kind of science that might find, say, climate change, or emerging pandemics.

That is absolutely not what they meant. Do you really, honestly think they're that stupid?

I think they think we are that stupid.

I think you (and others) are getting caught up in your own worse-case interpretation of the words of that statement, instead of looking at the intent of it. It is perhaps not the best wording but I think it's pretty easy to take that "megabytes per second per dollar" statement and choose to interpret it less poorly, and more like "having better, cheaper and more abundant useful data about yourself and your health".

Huh? You don't have to come up with an interpretation. The brief says it "looks a lot like today's MRIs but at nearly a hundred times the speed". They don't explain why having a hundred times as many MRI images would lead to better diagnostic outcomes. It is not like ultrasound scanning is a new idea, and they don't give any particular reason why this suggestion was not used before (other than "...data?")

> Beyond that, regulation is the next limit. Normally, for every diagnostic medical capability you need FDA approval. We’re starting by just giving you detailed body composition maps — and we’ll be submitting regular test results to the FDA for increased capabilities. This is just not how the FDA works. At all. You can't just email them slideware and marketing materials to keep them in the loop. You have to hire an a…

do they need FDA approval to have a good impact? it doesn't need to be a licensed medical device for me to interpret the data, and then verbally tell my doctor what's wrong this is similar to how people get a lot of medical value out of chatgpt today

You can't have any impact at all if you can't legally operate it or if you are hamstrung in your marketing claims.

Chatgpt is just words. This is an ultrasound imaging system. Who knows what could go wrong: blown out eardrums from feedback, acoustic burns, wild inaccuracies that lead to misdiagnosis.

There's really no way around documentation as a way of collecting evidence that the team knows what they are doing. Things like enumerating all the possible patient risks, assessing their severity, updating the design to mitigate, and ultimately testing that it works as intended.

This is why you can't just bolt on the medical device part. Most devs will have a conniption if suddenly expected to attend lots of meetings and do a lot of paperwork. Different skillset and very expensive to switch out your whole workforce.

Some initial thoughts as a practicing radiologist: - This looks really cool and I hope they keep innovating on this. I love seeing new modalities develop and despite my (many) reservations and criticisms, if even one good use case comes out of it that truly helps people, it's tech money well spent imo. - They show the reconstructed images as though they are a low resolution CT, and promise that quality will improve a…

this is why i always come to hacker news for the expert opinions. thank you for being critical yet optimistic.

> A) proactively keeping me healthy, and B) reactively helping get back to healthy when I am not

You want technology to train you how to avoid environmental factors and then give you treatment?

we're still very far away from eliminating humans in the loop from medicine.
