High-speed X-ray video captured with a Dectris photon-counting detector. I show how the process works and how this detector is different than normal camera detectors.

The sequence of tiff files directly from the sensor contain a lot of temporal flicker -- probably because the X-ray tube itself has time-varying output. This isn't so bad at 60Hz, but quite a problem at 300Hz. I used Resolve's "color stabilizer" to maintain constant levels throughout a clip, and was impressed how well this removed the flicker.
