Abstract:
1. A multi-positional computed tomography (CT) image producing method comprising the steps of: collecting data in a predetermined scan range using a helical scan that includes making a relative rotation of at least one of an X-ray tube and a multi-row detector around a subject to be imaged while making a relative rectilinear motion of the X-ray tube and the multi-row detector with respect to the subject to be imaged; extracting data from detector rows corresponding to reconstruction planes at a plurality of positions to generate respective data sets for a reconstruction, wherein all of the reconstruction planes are set in such a manner that the data of the detector rows corresponding to the reconstruction planes are acquired at each view angle within a predetermined view range; and producing respective CT images of the plurality of reconstruction planes based on the data sets.
