Abstract/OtherAbstract:
The helical scanning mode in computed tomography (CT) entails continuous table movement during image acquisition. The projections acquired in this mode will not be consistent with those in the axial scanning mode. A comparison of the helical and axial modes of scanning on the IGE HiSpeed Advantage CT system (software version ZA) has been made using a contrast-detail phantom. Differences seen between the two modes include shadow and streaking artefacts and an increase in the partial volume effect in the helical scan mode.
