Tomography

Imaging by sections or sectioning of the internal structures of an object as the human head through the use of any kind of penetrating wave:


Tomography

The word tomography is derived from the Greek tomos meaning slice and graphein which means to write.

A device used in tomography is called a tomograph, while the image produced is a tomogram.

X-Ray Computed Tomography (CT) is a medical imaging that uses tomography created by computer processing; digital geometry processing is used to generate a three-dimensional image of the inside of an object from a large series of two-dimensional X-ray images taken around a single axis of rotation.

A CT Scanner (computerized tomography scanner) is a special kind of X-ray machine that instead of sending out a single X-ray through the body as with ordinary X-rays, several beams are sent simultaneously from different angles. It was originally designed to take pictures of the brain; however, now it is used for taking pictures of virtually any part of the body. This scanner is especially good at testing for bleeding in the brain, brain tumors, brain damage, and for aneurysms (the condition in which the wall of an artery swells up).
