X-ray technology uses electromagnetic radiation to make images. The image is recorded on a7404Radiology film or radiograph, and is used to determine the type and extent of a fracture and to detect pathological changes in the lungs, stomach, intestines and other parts of the body. X-rays help physicians diagnose various diseases or ailments.
Plain radiographs are often called plain X-rays. Radiographs can be produced using a variety of imaging methods, and they all require exposing the patient to X-ray radiation. The image or picture is basically a shadow of the parts of the patient that absorb or block the X-rays. The image can be collected on photosensitive film, on a digital imaging plate, or seen live on a fluoroscope - sort of like an X-ray TV camera.

Radiographs are usually taken by a trained registered radiology tech. The resulting images are then interpreted by a radiologist who makes a diagnosis or suggests further tests.
Fluoroscopy, useful for catheter guidance, produces real-time images of the body employing a constant input of X-rays at a lower dose. Fluoroscopy is often used in image-guided procedures when constant feedback is required during the procedure.
