A CT scanner comprising a dynamic collimator disposed near an x-ray source and a controller configured to rotate the x-ray source about a subject, wherein imaging data is acquired from a single rotation of the x-ray source, the single rotation being divided into a first half-scan and a second half-scan. The controller is further configured to position the dynamic collimator after acquiring image data from one of the first half-scan and the second half-scan and simultaneous to commencement of acquiring image data from the other of the first half-scan and the second half-scan to obstruct a central portion of an x-ray beam emitted by the x-ray source during one of the first half-scan and the second half-scan. The CT scanner is further configured to reconstruct a CT image using the first set of imaging data and the second set of imaging data.
