jony10: in re: to your question ...



the x-ray beam is emitted from the source to the detector plate... because both spin on the same track the x-ray photons always strike the detector...

3rd generation CT scanners are the most prevalent...

often they might keep heavily used scanners spinning at a designated speed, the ones at sites or settings that get a lot of foot traffic, and just ramp up and then obviously emit when examining/when necessary.

here's 3rd generation CT spinning up to max speed...

the detector in this video is not a flat detector like what is used in cone-beam CT... it is how i described the routine, i.e., multislice/detector, CT 3rd generation detectors concave from isocenter and convex to the outter part of the gantry. it is the thing that looks like there are 5 cooling fans on it with it in a position near the top of the gantry in the beginning...
