Related to cross section: Scattering cross section

cross sec·tion

1. a planar or two-dimensional view, diagram, or image of the internal structure of the body, part of the body, or any anatomic structure afforded by slicing, actually or through imaging (for example, radiographic, magnetic resonance, or microscopic) techniques, the body or structure along a particular plane. Traditionally, "cross section" referred to views resulting from slicing at right angles to the longitudinal axis of the structure (axial or transaxial), but in contemporary use, the term is applied when the structure is sliced in any given plane;
2. the slice or section of a given thickness created by actual serial parallel cuts through a structure or by the application of imaging technique.

cross section

1 a transverse section cut through a structure.
2 (in nuclear physics) of a specific atom or particle at a specific radiation, the area perpendicular to the direction of the radiation that one attributes to the atom or particle.

cross section

A section perpendicular to the long axis of an organ.
