Why do CT scanners need to spin so fast?
In: Engineering
You can tell people “stay still”, but that doesn’t keep them from moving, they keep breathing, their hearts keep beating, and all that sort of stuff. If you take measurements slowly, there will be more motion between measurements. In the long run, you won’t be able to compensate for all of it, and the results will be less accurate. The faster you go, the less time for movement, and thus the less movement and the better the measurement data.
