A large, modern medical imaging machine, possibly a CT scanner, is situated in a clean and well-lit medical room. The machine is white with grey accents and features a circular opening with a long table extending from it, which can slide the patient in for scanning. On the side of the scanner, there are control panels with digital displays and buttons.
