Tomography
Imaging by sections or sectioning. Radiological imaging of serial planes (“cuts”) through an anatomical structure. A noninvasive technique designed to show detailed images of internal structures in a selected plane of the body. The scanning of a particular part of the body using X-rays or ultrasound. Procedure of making a radiographic image of a selected…

Tomograph
An apparatus that is used to create a tomogram. The machine allows for the movement of the film in one direction, while the source of radiation moves in an opposite direction to produce images at a targeted depth within the tissues. An x-ray tube attached to a Bucky diaphragm by a rigid rod allowing rotation…

Titanium oxide
Naturally occurring compounds of titanium and oxygen in various configurations. Chemical formula for titanium oxides are: TiO, TiO2, Ti2O3, and Ti3O5. Titanium oxide occurs naturally on the surface of titanium when it is exposed to air, and it is critical to osseointegration between living bone and a titanium implant.
