What effect does a pitch of less than 1 have on CT imaging?

When considering the impact of a pitch of less than 1 in CT imaging, the correct answer revolves around the concept of overlapping rotations. A pitch less than 1 means that the table moves less than the width of the slices being acquired, resulting in the acquisition of overlapping data for adjacent slices. This overlapping of rotations can enhance image quality since more data is collected from a smaller area, helping to reduce potential artifacts and improve the overall clarity and detail of the images produced.

In contrast to other implications of pitch, a value less than 1 contributes to improved resolution in the images, allowing for finer structural details to be discerned. This is essential in various diagnostic scenarios where the identification of subtle anatomical features is crucial.

The other options may suggest various outcomes associated with pitch in CT imaging, but they do not accurately reflect the effects specific to a pitch of less than 1, particularly as this setting is more focused on improving the image quality through the benefit of overlapping data acquisition rather than reducing scan times or radiation dose.
