Abstract

In the present paper a general and exact theory is presented that is valid for rotational panoramic radiography irrespective of the projection geometry and that incorporates non-rotational scanographic methods. The general theory includes as a special case the conventional approximate theory of the working principle of panoramic radiography. Complete analytical mathematical expressions including no approximations are derived for motion unsharpness and the geometrical properties of the panoramic image. Such exact expressions for motion unsharpness do not appear in the literature previous studies having made extensive use of approximations.
