Linear Tomography is the most basic form of tomography; it is a tomographic examination that is designed to image only that anatomy that lies in a plane of interest while blurring structures on either side of that plane. It is basically a procedure to obtain a sharper image, although this procedure is beneficial for better contrast images, it does have a higher patient dose.
Principals of Tomography
Equipment
The equipment used for Linear Tomography are similar to that of x-ray except that the tube and the film tray move in opposit directions; the top of the rod moves in one direction as the bottom moves in the opposite.
