Use of X-Ray machine to form a transparent perspective image of a spatial object (animate / inanimate) by passing X-Ray radiation through the item in question.
X-Rays and 2-D Radiography
Radiography involves irradiating the human body with small amounts of radiation, which are converted into images based on absorption across the field of illumination. There are two types of radiographic images used in medical imaging: projection radiography and fluoroscopy. Such 2-D projection techniques are still widely used despite advances in 3-D tomography, due to their lower cost, higher resolution, and often lower patient radiation dose.
This imaging modality, which uses a wide-field beam of X- rays, was the first (internal) imaging technique available to medicine in 1895, when it was named after its discoverer, physicist Wilhelm Röntgen.
