The use of radiography in osteological measurement

Radiographs provide a means of obtaining permanent images of objects. These images may be readily and repeatedly copied, disseminated or used in a variety of ways without the need further to disturb the original material. Although measurements are frequently taken from such images for metrical analysis, it must be remembered that these images are only representations of the original object. To obtain accurate data, one must be aware of the sources of error inherent in the image-forming process so that radiographs can be used in the appropriate way. This paper outlines the factors involved in the production of radiographic images and applies this to the generation of accurate metrical data.
