| 1. A CT imaging system comprising:
a gantry having an opening therein to receive a subject to be scanned;
a table in a movable relationship with the gantry; and
a controller configured to:
control relative movement between the subject disposed on the table and the gantry from a first data acquisition position
to a second data acquisition position;
determine a total scan time based on a first time for acquiring imaging data at the first data acquisition position and a
second time for transitioning from the first data acquisition position to the second data acquisition position; and
if the total scan time exceeds one cardiac cycle of the subject, then disable data acquisition in an immediately subsequent
cardiac cycle and re-enable data acquisition in the cardiac cycle following the immediately subsequent cardiac cycle.
