I have a similar feeling.

One the one hand its great that they are spending the time and money to do this, on the other hand I am _very_ suspicious of their motives.

Getting _a_ picture is not that difficult, getting an accurate, repeatable, high resolution picture is a lot harder, and state of the art.

my worry is two fold:

1) over promise and causing injury to desperate people who see smudges on scans and have invasive surgery only to find out that its a reflection/artefact

2) what are they doing with the data they collect, and how will it be used to make money.

I think the main issue is that there are "no good startups" any more. As soon as an innovation happens that might be worth something, your original CEO is replaced by someone driven entirely by money, rather than public good. Or they get bought out by a corp that only cares about maintaining a monopoly.

In the video David says he's building it just because he wants to. It really sounds like his own passion project. No investors. It's a nice position to be in.

Now I don't know this guy in the slightest. One view could be he's just a geek like us living out his dream building cool potentially useful stuff not entirely sure where it will lead.

A cynical view is it's all about $$$$.

Either way it's great HN content!

I should have made clear, my suspicions are not really around the engineers running this, its the people who are less motivated by the original cause that can see $$$ in it.

Thats the point right, most of us would, if given the chance, divert some funding to work on a passion project that could easily save lives. That I applaud and would love more people to be able to do.

We have no investors, we could pocket the money. We're choosing instead to spend it on projects like this <3

Can't wait to read your papers and/or watch your videos where you show us :).

as I said, an image is doable, there is opensource to do that: https://hackaday.io/project/159467-open-source-ultrasonic-ph...

accurate and repeatable is that hard bit.
