Just a nit-picky detail; in human CT scanners it's usually a (linear) array of 2D detectors, not a line-detector.
- mikewarot 4y agoso they're actually doing 2d data capture.. oh... that makes sense... otherwise you waste all the x-ray that went through the patient slightly off the plane of the circle. We don't want to waste X-ray exposure, do we?
