Is it just me or did the tonality in this one change towards an infomercial?

They always were supposed to be for marketing, but I did like their in-depth technical analysis. I imagine that took a lot of work/time to write up though. I'm okay with them skipping that sometimes to get more public scans out for me to enjoy. But I also would love their analysis as well!

One thing I really enjoyed about the analysis was how it really explained the nuance of the technology they sell, and there were always lessons in it for how to tweak the machines on different objects/materials, and how to interpret things, and why certain areas looked the way they did.

For example, on the Omnipod[0], why can't I find an attenuation window to see how much medicine is left inside the reservoir? Is it empty? Is the medicine too low in attenuation to be seen? Is the medicine too similar in attenuation to the outer casing to isolate from it? Could it be isolated if the machine were set up / configured with different settings, and if so, what are the tradeoffs?

Could be, the company behind the website would like to sell you an industrial CT scanner.

I dont want CT scans of wearables. I want wearables that can do CT scans.

That is not even close to feasible with today's level of technology, and will not be for quite some time.

well, maybe wearables that provide some sort of internal visual scans. But with CT scans delivering 70 times the radiation of a typical x-ray, I think I'd prefer not wearing a portable chernobyl.

Maybe a wearable ultrasound instead?

edit: after a little informal side-searching after posting this, I've learned that people working at Chernobyl, not in the reactor directly, but elsewhere in the sprawling site received anywhere from 1 to 100 CT scans worth of radiation. The firefighters that were on the roof received anywhere from 100 to 1,600 CT scans worth of radiation.

> Maybe a wearable ultrasound instead?

If one is concerned about the potentially damaging effects of radiation, and the relative safety of ultrasound technology springs to mind, then one may be also interested in reading more about the apparently forbidden topic of ultrasound safety studies, if such a person can get past the cognitive dissonance from having been told the consensus opinion on how safe ultrasound is, e.g.:

The jury may still be out?

I personally prefer to approach the topic of "safety" by considering the trade-offs. The knowledge gained through ultrasound significantly outweighs potential risks associated with it.

People still continue to play the lotto thinking they will win, and they reject statistically low risks in lieu of a greater risk created by avoidance. See: any vaccination topic.

When shifting into the topic of a wearable though, the extreme amount of time alone amplifies the risks into outright dangerous levels. I did not seriously believe ultrasound to be safe to that level.

The time, and also the proximity.

As I understand it, the potential dangers of a lot of these kinds of things dissipate quite rapidly with distance.

But with wearables, the emitters are quite literally strapped against the body (practically zero distance).

All of those links are for the same book from 2015 (the fourth isn't direct to the relevant article but it's easy to find on the page). Has there been any new information since then?

The 50 studies in the cited 2015 book ought to span a range of time, and their keywords could be used to search literature for more recent material.

> Has there been any new information since then?

Since you asked, there apparently was a 2017 followup book by the same author. These links are for that book:

That book claims:

> Microcephaly incidence increased 1000x within the area of The Network. This was first observed seven months after The Network began its remote prenatal ultrasound program. Do the math.

Almost every baby is exposed to prenatal ultrasound. What do you think was different about that ultrasound program? Why would prenatal ultrasound cause microencephaly there, but not everywhere?

> not everywhere?

Are you absolutely certain that there is not an unexplained uptick in brain damaged newborns/children in the USA?

And that its cause is not some thing(s) that "almost every" one of them is subjected to repeatedly?

And that it is not just a case of better/more/over diagnosis?

IDK about by you, but there are literal nurseries/schools for the brain-damaged kids popping up on Main Street. That's how many there seem to be.

So yeah, maybe they're not in that study. But that means they don't exist?

I don't think that's comparable to what happened in Brazil at that time.
