Abstract: A radiation imaging system includes a radiation detector for detecting radiation emitted from a radiation generator; a quick-connect unit configured to activate the radiation generator to initiate radiation emission and to activate the radiation detector to initiate detection of the radiation; and a notification unit included within the quick-connect unit that is configured to notify an operator of a time when the radiation detector is ready to detect the radiation. The quick-connect unit is connectable to the radiation detector and the radiation generator without having to make hardware modifications therein. In an alternate embodiment, the quick-connect unit is a handswitch to be held by an operator, where the notification unit notifies the operator that the radiation detector is ready to detect the radiation, by emitting at least one of a visual signal, a tactile signal and an audible signal.
