I doubt it. How can you image an organ at home when you're not even 100% sure exactly where that organ is? Or what it looks like on an ultrasound? And that's not even getting into knowing whether you're looking at them from the right angle for the images to be diagnostically useful.
Yeah - my experience of watching baby ultrasounds was that I had no idea what I was looking at until the technician told me. Maybe there's an occasional clear image of a head or nose or something, but the rest of the time it's just wobbling grey shapes. I can't imagine trying to do that myself - let alone looking at my own organs which are mostly just amorphous blobs, and trying to diagnose something.
I suspect the main cost in running a diagnostic scan is labour rather than capital - and these low cost ultrasound devices will only have an impact in the developed world if they go hand in hand with AI.
Obviously they'll make a huge difference in developing countries where labour is relatively cheap compared to equipment - but even then it'll still require trained professionals to operate.
