Tomographic Movement

As the tube moves across a distinct plane of interests which can be transverse, sagittal, coronal or hypocyclodial in which radial and circular motion are both employed to gain a radiographic image. The circular motion is the path the x-ray tube to film takes is basis for how linear tomography functions.

The Children of Linear Tomography

Linear Tomography doesn't really have too much useful application in diagnostic imaging anymore these days except for imaging renal stones but it's children CT, MRI, PET, SPECT and the new hybrid PET/CT have seen an abundance of patient's that reach to the gods

The Versatile Angle

The tomographic angle can not only go transverse but it can go in more than one direction depending on the plane of interest that the anatomical part is on

Hypocycloidal tomography

Hypocycloidal Tomography is form of tomography in which the X-ray tube and film move in a hypocycloidal path. Conventional tomography can be made using several movement patterns for the X-ray tube and the film. The common linear movement is mechanically easy to produce but will give rise to rather thick tomographic sections and a short blurring path (the length of the tomographic section).

Linear Tomography

aka Conventional Tomography is performed with a linear movement of the focal spot and the X-ray detector (film-screen system).

Guess what part of the cranium this is you get a free lunch!!!!!!

Intro to linear tomography

For those new the world of diagnostic imaging what you are viewing here is Linear Tomography aka body section radiography aka planigraphy aka laminography aka stratigraphy, is the process of using motion of the X-ray focal spot and image receptor (e.g. film) in generating radiographic images where object detail from only one plane or region remains in sharp focus (Fig. 1).
