1. A method for providing computed tomography (CT) imaging, the method comprising: acquiring gated cardiac information by sensing electrocardiogram (ECG) signals over multiple cardiac cycles; providing a patient table to move along an examination axis of a rotating gantry of a CT imaging system having at least one imaging detector, the imaging detector including a pixelated detector array; configuring the CT imaging system to perform an overlapping helical CT scan by controlling a speed of the moving patient table along the examination axis through a field of view (FOV) of the at least one imaging detector of the rotating gantry and a rotation speed of the rotating gantry to be synchronized with gated cardiac information, wherein each rotation of the rotating gantry is synchronized to occur within a select number of—cardiac cycles for a patient being imaged, wherein the select number is at least three; and configuring the CT imaging system to adjust the speed of the moving patient table based on a heart rate of the patient as indicated by the ECG signals.
