Those analogic scanners are indeed nationwide, and also hated by many travellers, because they're slow. They're CT scanners, which like a medical scanner means 3D images... Which take longer to interpret.
Plus, every individual thing needs to go in a bin, and with multiple "loading stations", there's still only one output. Granted your 3-1-1 and laptops can stay in, but they're a pain. Given the choice of a lane with these vs a lane without, I'm going for the lane with the old X-ray scanners.
