In CT imaging, what is the term used for the thickness of the slice taken?

In CT imaging, the thickness of the slice taken is referred to as slice thickness. This measurement is crucial because it affects the amount of detail in the images produced. A thinner slice thickness can provide higher resolution and finer detail, which is especially important when trying to visualize small structures or lesions. Conversely, thicker slices may result in faster image acquisition but can sacrifice some detail and resolution.

Understanding slice thickness is essential for making appropriate selections during the imaging process. It directly correlates with the quality of the diagnostic information that can be extracted from the CT images and influences factors such as spatial resolution and potential artifacts.
