Image Distortion in Rotational Panoramic Radiography

A theoretic analysis of the distortion and displacement of the inner structures of three-dimensional objects in panoramic films has been performed. Mathematical calculations were carried out of the distortion of model structures simulating structural details in an object. Although the model structures are affected by the distortion effects inherent in rotational panoramic radiography, the panoramic film still gives a recognizable image of the inner structure of an object.
