Definitely the right solution
Special CT scanners are used during the check-in process at airports. These are characterised, inter alia, by their large internal diameter of up to two metres. The transmission of image and signal data can be contacting or contactless depending on the requirements. When scanning hand baggage, rotating CT systems have a decisive advantage: It is not necessary to remove fluids and laptops from the baggage, but they can still be checked for explosives and other substances much more reliably – if a slip ring lends a helping hand.
