Why do CT scanners need to spin so fast?
In: Engineering
They don’t. But the speed they can make the image, and hence how quickly they can get results, how many machines you need to buy for a particular patient load, how much each CT scan costs, etc. all scale with how fast it spins.
A faster spinning machine is more productive, more efficient, and produces results faster (can be important for some conditions).
It’s like asking “why do cars need to go so fast?” They don’t, but we’re all happier with faster cars up to the point that safety starts to get compromised.
