Miss Allisson Summer-field for their collective help and encouragement. I am indeed fortunate It is easy to forget the help provided with the to work with such an able and supportive team.
Dr Neil Lewis duced in the first place. Understanding the nature of the shadowgraph and interpreting the information contained within The range of knowledge of dental radiography it requires a knowledge of: Understanding the radiographic image is central to the entire subject.
The image is produced by X-rays passing through an object and interacting with the photographic The final shadow density of any object is thus emulsion on a film. This interaction results in affected by: The image shows the various black, grey and white radiographic shadows. A plaster of made from plaster of Paris, ii Plan view shows the Paris, B hollow plastic, C metal, D wood, iii Radiographs cylinders have varying internal designs and thicknesses.
The radiographic image 5 D Fig. The main limitations of viewing the two- dimensional image of a three-dimensional object The three-dimensional anatomical tissues are: Therefore, when viewing two-dimensional radiographic images, the and shape of structures within an object.

Periodontal ligament space Lamina dura Trabecular pattern Fig. The radiographic image 7 Front view Side view Plan view Fig. The side view shows that there is a corridor at the back of the house leading to a tall tower. The plan view provides the additional pieces of information that the roof of the tall tower is radiologt and that the corridor is curved. Erix the overall shape the architect to describe the whole house from the front view alone.
To visualize all aspects of any three-dimensional object, it must be viewed from several different Superimposition and assessing the location positions. This can be illustrated by considering and shape of structures -within an object an object such as a house, and the minimum infor- mation required dadiology an architect is to draw all The shadows cast by different parts of an object aspects of the three-dimensional building in two or patient are superimposed upon one another dimensions see Fig.
Unfortunately, it is only on the final radiograph.

To expect one where a particular internal structure lies, or to its radiograph to provide allthe required information shape, as shown in Figure 1.
This positioning lowers the dense bones of the base of the skull and raises the facial bones so avoiding superimposition of one on the other. A radiopaque white object arrowed can be seen apparently in the base of the right nasal radiolohy.

Eroc of the recently developed alternative views may still not be able to provide all the radiologg specialized imaging modalities described in desired information for a diagnosis to be made Chapter 17 have been designed to try to overcome see Fig. The radiopaque white object arrowed now appears intracraniallyjust above the skull base.
It is in fact a metallic aneurysm clip positioned on an artery in the Circle of Willis at the base of the brain. The dotted line indicates the direction of the X-ray beam required to produce the radiograph in Figure 1.

This produces a similar image in each case containing a mass in a different position or of a different with no evidence of the mass. The information obtained shape. In all the examples, the mass will appear as a similar previously is now obscured and the usefulness of using two sized opaque image on the radiograph, providing no views at right angles is negated. B The lateral or side view radioogy a possible solution to the problems illustrated in A; the masses now produce different images.
Quality of the radiographic image Overall image quality and the amount of detail These factors are in turn dependent on several shown on a radiograph depend on several factors, variables, relating to the density of the object, the including: They are discussed in greater detail in Chapter These ideal whaits are shown diagram- matically in Figure 1.
The effects on the final image of varying the position of the object, film or X-ray beam are shown in Figure 1.
