X-ray computed tomography, or simply computed tomography (CT), is an imaging method using X-ray transmission and computer algorithms to reconstruct two-dimensional (2D) images of an object, representing object’s slices. These images can then be processed to compute a three-dimensional (3D) reconstruction of the object’s structure, including inner geometries.
In this context the term “tomography” refers to nondestructive imaging of sections. The term derives from two Greek words: “tomos,” meaning “section,” and “graphein,” meaning “to write.”
Although the term “computed tomography” is very general and could refer even to tomographic techniques not using X-rays, in practice it usually refers to the computation of tomographic images by X-ray transmission. The term “X-ray computed...
