Radiography is a medical imaging technique that utilizes electromagnetic radiation, such as X-rays, to create visual representations of the internal structures of the body. The principle involves passing a controlled beam of radiation through the body, where varying levels of tissue density attenuate the beam to different degrees. These differential attenuations are then captured by specialized detectors, producing a differential image. This diagnostic method is essential for visualizing bones, examining the chest cavity, and evaluating various internal tissues, assisting practitioners in the detection of fractures, foreign objects, and structural anomalies. The technology has evolved significantly to improve image resolution and reduce radiation exposure while maintaining diagnostic accuracy.
