Abstract
A control circuit for a computer-aided tomography (CT) system includes an input that receives a master timing signal and an input that receives a first timing signal. The control circuit includes a mode detection circuit that determines the scan mode of the CT system based on the master timing signal and a first timing signal, where the frequency of the first time signal is lower than the frequency of the master timing signal. The control circuit also includes a circuit that generates a second timing signal based on the master timing signal and the scan mode, where the second timing signal that has a lower frequency than the master timing frequency but a higher frequency than the frequency of the first timing signal.
