How Are Plain X-Rays Different From Other Imaging Modalities?
Plain radiographs are often called "plain X rays" - but you can't see the X-rays, only the images created by them. 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 flouroscope - sort of like an X-ray TV camera.
The radiographic image is a "photographic negative" of the object - the "shadows" are white regions (where the X-rays were blocked by the object). The image is black in the regions that did not stop the Xrays, and they passed through to expose the film or sensor.
Plain radiographs ("plain films") are usually taken by a trained Radiologic Technologist. The resulting films or images are then interpreted by the Radiologist to make a diagnosis or suggest further tests.
I hope I have added a new knowledge on you today.
