#12A Motif interface from the early 90s at about 10:00 in the video. That X-Ray detector has probably a very long history.

#13I may have the opportunity to use a much higher framerate camera in the future. Please leave suggestions for things that are fairly transparent to x-rays (no metal, or very thin small internal parts), and demonstrates the utility of high speed capture (typically things breaking, bouncing, shattering). The last requirement is that the object be very small, just 1 to 2 cm long. Since learning about ptycography, I may t…
I thought the insect breathing work at the synchrotron was cool https://www.science.org/doi/10.1126/science.1078008

I wonder if you could blow some fine mesh aluminum/iron powder through a small whistle to see any of the airflow effects.
Spurious xray emission from triboelectric effect.
Phase change of various materials changing absorption characteristics.
Capacitor discharge.

#15Not only is this incredibly cool, but it bridges my knowledge of x-ray (CR/XR, in this case, DR) even further. I work for a medical imaging company and we actually sell and promote our digital radiography machine that will do this, but for humans (at a much, much slower rate, but enough to be useful in medical diagnostics). I had never considered an application of use outside of medicine. So, my day is now accounted…
Please post a link to your YT channel so we all can take part in the fun.

This may be a bit hard, but jumping insects like locusts and crickets?

Here's an interesting one, if the equipment is sensitive enough you could test if you can see the difference in air densities as a .22 caliber bullet passes by.

#18I got nervous watching him put his hand in front of the machine. You don't want to subject yourself needlessly to ionizing radiation. A little here and there is probably okay at small doses and for valid reasons, but it all adds up over a lifetime. He didn't mention how much X-ray radiation this puts out in the first half or so of the video. I worry it's more than a medical photograph as it's continuous high sample r…
>I worry it's more than a medical photograph as it's continuous high sample rate video, but I'm not an expert. Would be curious to know. Typical fluoro skin entrance exposure rate to go through someone's hand is on the order of 1-3 millisieverts per minute. With a more advanced detector (like this one) it may be lower, but increasing the frame rate or resolution will tend to require higher dose rate. The associated r…
I've wondered how much the average X-ray dosage dropped since they stopped using film and switched to detector-based imaging. Anyone know?
