The term “tomography” is composed of the two Greek words “τόμος“, which can be translated as “cut” or “slice” and “γραφία” which is the Greek term for “picture”. The image that is produced by a tomograph is called a tomogram. In order to achieve information from a tomogram, one needs to reconstruct the data set by using a reconstruction algorithm, which then computes the tomographic slices of the object. These slices can be stacked together and form a 3D stack of the object of interest.
