X-rays | Radiology Reference Article | Radiopaedia
X-rays (or much more rarely, and usually historically, x-radiation or Roentgen rays) represent a form of ionizing electromagnetic radiation. They are produced by an x-ray tube, using a high voltage to accelerate the electrons produced by its cathode. The produced electrons interact with the anode, thus producing x-rays.

Image Formation and Radiographic Quality | Radiology Key
To produce a radiographic image, x-ray photons must pass through tissue and interact with an image receptor (IR) (a device that receives the radiation leaving the patient), such as an imaging plate in computed radiography (CR). Both the quantity and the quality of the primary x-ray beam affect its interaction within the various tissues that …
Panoramic Dental X-ray
What is Panoramic X-ray? Panoramic radiography, also called panoramic x-ray, is a two-dimensional (2-D) dental x-ray examination that captures the entire mouth in a single image, including the teeth, upper and lower jaws, surrounding structures and tissues.. The jaw is a curved structure similar to that of a horseshoe. However, the panoramic x-ray …
Introduction To Radiographic Testing(RT).
It records the transmitted X-ray /Gamma Rays from the Test item and gives a radiographic image. In film-based radiography, the films used to consist of a Polyester base with silver bromide and emulsion of gelatin coating bonded with the polyester base using an adhesive on both sides. When transmitted Radiation hits this film.
X-ray | Definition, History, & Facts | Britannica
X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10^-8 to 10^-12 metre. The passage of X-rays through materials, including biological tissue, can be recorded. Thus, analysis of X-ray images of the body is a valuable medical diagnostic tool.

Radiography & X-ray Imaging | Let's Talk Science
Radiography is the creation of images using x-ray energy. Images created using this technique are called radiographic images (or radiographs ). X-ray images are still pictures similar to photographs. Fluoroscopic images are moving pictures similar to movies. Tomographic images are visualized 'slices' of the body.
