One more look at the mandibular condyle.

A great deal of attention has been given over the years to the development of highly specialized x-ray equipment that, in many instances, has reduced the complex nature of the radiographic procedure. However, it is impossible, and probably always will be, to design equipment that will automatically produce the proper radiographic position. This will remain a distinct function of the technologist, and the individual's skill will have great bearing on the quality of the radiograph. One need only review the literature to realize how innovative our profession has been in developing countless numbers of radiographic positions for demonstrating specific anatomical regions. Moreover, many useful radiographic positions can be found that, for various reasons, never gained the level of acceptance perhaps anticipated by their originators. Consequently, the practical value of these positions often escapes our attention. To illustrate this point, I have selected a radiographic position described some thiry years ago for visualization of the mandibular condyle. It is my intent to demonstrate the practical value of this projection, as well as that of some others not usually thought of, for radiography of the mandibular condyle.

The use of an inverted Kodak X-Omatic cassette as an improvised grid.

An inverted X-Omatic cassette is particularly useful when substituted for a grid in situations where the employment of a grid would not be practical. It also provides a selective filtration effect during radiography of anatomical regions that exhibit a wide range of subject opacity. With radiology procedures and equipment becoming more complex, the concept of employing an improvised method of controlling radiation scatter may seem antiquated when compared to today's high standards of imaging excellence. However, based on my experience with this method, I feel its practical application should not be overlooked as an alternative method of coping with an age-old problem of radiation scatter control.
