cross sectionnoun
a flat plane cutting through a three-dimensional object, usually at right angles to the longest axis of the object.
cross sectionnoun
any visual representation of a cross section, showing the internal structure of the object in the plane of the cross section; as, the technician prepared a series of MRI cross sections of the skull. Different cross sections created by different techniques may show different aspects of internal structure. Thus computerized axial tomography using X-rays shows different structures than are visualized by MRI.
cross sectionnoun
a thin slice of an object made by cutting it transversely; as, to view a cross section of a bacterium with an electron microscope after staining the DNA; cross sections were prepared with a microtome.
cross sectionnoun
a representative sample of a complex group; as, the town contained a cross section of the American population.
cross sectionnoun
(Physics) a measure of the probability that a nucleus will interact in a specified way with a bombarding particle, expressed as the effective area that the nucleus presents to the particle; -- called also nuclear cross section.
cross sectionverb
to create one or a series of cross sections by cutting (an object) into thin slices.
Wiktionary

cross section
In physics, a cross section is a measure of the probability that a specific process will take place when particles interact. This is usually represented in terms of an effective area that a given particle presents as a target for another particle. In general terms, a cross section can also refer to a slice or a view of an object, system, or phenomenon that is cut along an axis to reveal what's inside or to understand a relationship in a systematic way, which is widely used in many fields including architecture, geology, anatomy, and engineering.

Cross section
In geometry, a cross section is the intersection of a figure in a 2-dimensional space with a line, or of a body in a 3-dimensional space with a plane, etc. When cutting an object into slices, one gets many parallel cross sections. Cavalieri's principle states that solids with corresponding cross sections of equal areas have equal volumes. The cross-sectional area of an object when viewed from a particular angle is the total area of the orthographic projection of the object from that angle. For example, a cylinder of height h and radius r has when viewed along its central axis, and when viewed from an orthogonal direction. A sphere of radius r has when viewed from any angle. More generically, can be calculated by evaluating the following surface integral: where is the unit vector pointing along the viewing direction toward the viewer, is a surface element with an outward-pointing normal, and the integral is taken only over the top-most surface, that part of the surface that is "visible" from the perspective of the viewer. For a convex body, each ray through the object from the viewer's perspective crosses just two surfaces. For such objects, the integral may be taken over the entire surface by taking the absolute value of the integrand and dividing by two:

Simon Karger from technology developers:
With Chimaera, what we've done is we've combined smart sensing technology, pre-operative planning, we've taken small implant form-factors; and we've combined both implant delivery with surgical tool to provide a completely connected, unified surgical system that has the potential to take a surgery that maybe only four or five people in the world can carry out today and make it accessible to a broad cross-section of general surgeons. By doing that we make it accessible to a much, much broader patient population.
