In quantitative densitometry it is essential to understand the statistical and systematic errors which contribute to the difference between the true and observed densities of anatomic structures. To study these we have developed two types of low contrast phantoms: in one type the contrast with the surrounding medium is generated by electron density difference, in the other type the contrast arises from atomic number difference. The resulting densitometric errors in a digital fluorography unit arising from system nonlinearities and drifts, image field distortions, image field intensity nonuniformities, image noise, generated contrast, point response function, beam hardening and subject scattered radiation are presented and discussed.
