NettetThe multi-slice CT scanner refers to a special CT system equipped with a multiple-row detector array to simultaneously collect data at different slice locations. The multi-slice CT scanner has the capability of rapidly scanning large longitudinal (z) volume with high z-axis resolution. It also presents new challenges and new characteristics. In ... Nettet11. apr. 2024 · The slice thickness is very fine (of the order of a 0.25 mm) and I’d like reformat the stack to a thicker slice thickness (e.g. 2.0 mm). Very crudely, this would be roughly equivalent to reducing the number of slices by replacing every 8 slices with the average pixel value across all of the 8 slices.
