A radiograph is a photographic image that is produced on a surface area that is radiosensitive. This is done by radiation instead of visible light specifically by using x-rays or gamma rays. Plain radiographs are frequently known as plain x-rays. These radiographs are produced with the use of number of imaging methods that requires the patient to be exposed to the x-ray radiation.

The image that is formed is usually a shadow patients different body parts that have the capacity of absorbing or blocking the x-rays. This image is collected on a digital imaging plate, on a film that is photosensitive or can be observed live on a fluoroscope. Fluoroscope is a type of x-ray TV camera.

The image formed by the radiographs is called as “photographic negatives” of the object. This is because the shadows appear white as the x-rays were obstructed by the object; whereas the image appears black as the x-rays were allowed to pass through the object for exposing the film. The radiographs are taken by a skilled and a registered radiologic technologist. The resulting image is interpreted and studies by the radiologist for making a diagnostic solution as well as planning further course of treatment.

The radiographs are usually observed on a light-box. Nowadays, the radiographs are digitized and then observed on a monitor having high resolution. A proper condition for viewing is a significant factor to interprete the radiograph. Although interpreting is a skill that is mastered through time and experience, use of proper equipments and consistent process of evaluation increases the possibilities to detect the defects.

There are a number of detectors used in the process. These detectors include semiconductor diode, scinitillator and a photographic film that are used greatly for collecting the images. Also the sources of x-ray photons are used such as betatrons, x-ray tubes and linacs. Radioactive source like the lr is used for the gamma photons.

Sometimes dental radiographs may be recommended your dentist. It displays the condition of the bones around the roots as well as the length and the shape of the roots. These dental radiographs are very crucial to finalize the further steps of diagnosis.
