I’m more accustomed to the science coming from photon-counting x-ray telescopes, not so much being the target of a photon-counting x-ray microscope, but … 🤷‍♂️

Anyway, a CT scan was just part yesterday’s emergency visit to the urology department of the Heidelberg University Clinic 😬

A pretty miserable way to spend seven hours on a Saturday, so do yourselves a favour:

Drink more water, folks 🚰
No, more than that 🚰🚰
Keep going 🚰🚰🚰✌️

FWIW, to satisfy the geek in you, this particular CT scanner was a Siemens Somatom Edge Plus. It emits 70-140keV x-ray photons which are converted into visible photons using a ceramic scintillator material & registered by CMOS arrays with built-in A/D converters, in Siemens' Stellar-Infinity detector. The scanner takes 128 slices in a few seconds, has a 0.3mm spatial resolution, & the drum rotates at over 200rpm.
