Abstract
An imaging system (100) includes a stationary gantry (102), a rotating gantry (104), a radiation source (110), and a detector array (112). The detector array detects radiation for a plurality of integration periods during a rotating gantry revolution, the plurality of integration periods corresponds to different angular position ranges, and the detector array generates a signal indicative of the detected radiation respectively for the plurality of integration periods. The system further includes an integration period controller (118) that generates an integration period timing signal that includes timing for a start of each of the integration periods for a revolution of the rotating gantry based at least on a time duration of a previous revolution of the rotating gantry around the examination region, wherein the integration timing signal is used trigger the plurality of integration periods.
