Interslice

Interslice is a term used in several disciplines to denote an element or region that lies between consecutive slices in a layered or segmented structure. Because it is applied across diverse fields, the exact definition of interslice varies by context and is not standardized.

In medical imaging, interslice refers to the spacing between sequential image slices, such as CT or MRI. This interslice gap influences the ability to reconstruct three-dimensional volumes, affects spatial resolution along the slice direction, and can introduce partial volume effects when the gap is large.

In materials science and additive manufacturing, the term describes the region or boundary between deposited layers or slices of material. The interslice properties, such as bonding, porosity, and surface finish, depend on process parameters and influence the strength and anisotropy of the final object.

In data processing and visualization, interslice can describe a conceptual bridge between two data slices in a multi-dimensional representation, sometimes used in slice-based algorithms, windowing, or rendering pipelines.

Etymology: the term is formed from the prefix inter- meaning between and slice. It appears in technical literature where layered or segmented data are discussed.
