Compensation of differences in density of radiographs by densitometry.
Radiographs were made of a dried human mandible with variations in kilovolt peak, exposure time, soft-tissue thickness substitutes, and developing time. The densitometric measurements of the image of dental and bony structures were transformed into millimeters of aluminum equivalents by means of densitometric measurements on the penetrometer. Variations in kilovolt peak, exposure time, soft-tissue thickness substitutes, and developing time do not affect the densitometric measurements after transformation, except when radiographs are very dark.
