Radiology techniques

Similar to the images produced in 1895, conventional radiographic images (usually shortened to X-rays) are produced by a combination of ionizing radiation (without added contrast materials such as barium or iodine) and light striking a photosensitive surface, which in turn produces a latent image that is subsequently processed.

The major advantages of conventional radiography are relative inexpensiveness of the images and the possibility to obtain them virtually anywhere by using mobile or portable machines (for example, mammography). Disadvantages are the limited range of densities it can demonstrate and the use of ionizing radiation.
