title: Form distortion in narrow beam rotation radiography.
abstract: The distortion of morphologic object elements, for distortion, at the exposure of a panoramic image has been determined mathematically and experimentally. As models the square, the circle, the rhomb, and the equilateral triangle were used. The general characteristics of the form distortion in narrow beam rotation radiography are analysed and described.
