➡️ LESSON DESCRIPTION:
This lesson’s objectives are to define shape distortion, foreshortening, elongation, and the law of isometry. This lesson also explains the impact of shape distortion on the radiographic image and image interpretation. This lesson also explains the causes of foreshortening and elongation and describes how to avoid shape distortion. This lesson also describes how shape distortion can be used to better visualize anatomy of interest.

Most radiographers believe that changing the tube angle will change the geometrical relationship between tube focus and patient. This prevents perfecting radiography to an art form as it locks practitioners into following instructions devised 100 years ago.
