Radiation Protection in Radiography
The images in radiography are created by passing an X-ray beam through some section of a patient’s body. They are recorded either on film or some form of digital media. Generally, the images recorded on film are viewed as transparencies on a lighted view-box or illuminator and the digital images are viewed on computer displays.
The general trend in the world is a transition from film-based to digital radiography. While digital radiography offers definite advantages, it might not be the most appropriate choice at this time for many clinical facilities because of cost and other operational considerations.
It is important to recognize that the major factors of image information and radiation exposure to patients are not determined by the type of radiography (film or digital) but by the selection of the imaging system characteristics and operating factors for each clinical procedure.
