1. A computed tomography system, comprising: an x-ray source that rotates about an examination region and translates along a longitudinal axis, wherein the x-ray source remains at a first location on the longitudinal axis while rotating about the examination region, accelerates along the longitudinal axis to a scanning speed, and performs a fly-by scan of a region of interest in which the x-ray source concurrently rotates about the examination region and translates along the longitudinal axis while at least one hundred and eighty degrees plus a fan angle of data is acquired; at least one detector that detects x-rays radiated by the x-ray source that traverse the examination region and generates signals indicative thereof; and a reconstructor that reconstructs the signals to generate volumetric image data.
