ABSTRACT:
A computed tomography system (100) includes an x-ray source (112) that rotates about an examination region (108) and translates along a longitudinal axis (120). The x-ray source (112) remains at a first location on the longitudinal axis (120) while rotating about the examination region (108), accelerates to a scanning speed and performs a fly-by scan of a region of interest (220) in which at least one hundred and eighty degrees plus a fan angle of data is acquired. At least one detector (124) detects x-rays radiated by the x-ray source (112) that traverses the examination region (108) and generates signals indicative thereof. A reconstructor (132) reconstructs the signals to generate volumetric image data.
