ABSTRACT:
A method for modifying a planar image slice in a CT scanner having a predetermined reconstruction angle, comprising: reconstructing an image of the slice using initial X-ray attenuation data acquired along an initial scan path sector; acquiring additional X-ray attenuation data along an additional scan path sector in a vicinity of the axial position of the slice, the sector having an angular extent substantially less than the reconstruction angle; and modifying the image, to provide a modified image of the slice, responsible to the additional attenuation data.
