On November 8, 1895, William C. Roentgen discovered the x-ray. About half a month after the announcement of this discovery Friedrich Otto Walkhoff took the first dental radiograph. It took him 25 minutes to get his own radiographic image. Since then, technological advances have dramatically improved radiographic image quality. However, the way the radiographic image quality is affected by the X-ray beam quality, quantity and intensity, and by the radiographic object, have not changed.
The purpose of this course is to explain the factors that are responsible of forming the radiographic image and how they affect the image quality.
