A new formulation of total unsharpness in radiography. 1977

A A Harms, and A Zeilinger

A new formulation of total unsharpness in radiography based on line spread and edge spread function analysis is established and investigated. The unsharpness contributions due to (1) screen conversion, (2) object motion and (3) geometric effects are incorporated into a general integral formulation. Comparisons with experiments are undertaken and the ambiguity, as well as limitation, of a widely used empirical unsharpness formula is clarified.
