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.
