Among Us is a social deduction game developed by Innersloth and released in 2018, which became widely popular in 2020 through streamers and short-form video. The Medbay scan is one of its visual tasks, performed in the medical bay on the Skeld map, where a crewmate stands on a scanner while other players can watch. Because the scan cannot be faked by the impostor in the original version, it became a shorthand for innocence in memes and edits, and creators still use the sound to signal that someone has been cleared.
