Bertha Röntgen's hand, one of the first x-rays

The x-ray machine is a machine used to produce x-rays.

1 History

X-rays were discovered by Wilhelm Röntgen ( 1895).

X-rays are produced by bombarding a surface with high speed electrons (in vacuum)

The first x-ray photograph was made of the hand of Röntgen's wife. The image displayed both her wedding ring and bones. On January 18, 1896 an X-ray machine was formally displayed by H.L. Smith . Upon discovery in 1895, X-Rays were advertised as the new scientific wonder and seized upon by entertainers. Circus patrons viewed their own skeletons and were given pictures of their own bony hands wearing silhouetted jewelry. While many people were fascinated by this discovery, others feared that it would allow strangers to look through walls and doors and privacy.

Early x-ray machines were used in stores to help sell shoes. These were known as fluoroscopes. However, as the harmful effects of X-ray radiation were discovered, they fell out of use. (They were more a clever marketing tool to attract customers than a fitting aid. Shoe-fitting use of the device was first banned by the state of Pennsylvania in 1957Events January January 2 San Francisco and Los Angeles stock exchanges merge.

2 How They Work

X-ray machines work by generating a beam of x-rays. The beam is projected on matterMatter is anything that has mass and occupies space. One [contemporary] view on matter takes it as all scientifically observable entities whatsoever. Matter can more accurately be defined as the energy that has a low vibratory rate, a compressed energy st. Some of the X-ray beam will pass the object. The resulting shadow patternA pattern is a form or model (or, more abstractly, a set of rules) which can be used to make or to generate things or parts of a thing, especially if the things that are generated have enough in common for the underlying pattern to be inferred or discerne of the radiation is then detected by photographic film, semiconductor plates or image intensifiers. ImageIn common usage, an image (from Latin imago or picture is an artefact that reproduces the likeness of some subject—usually a physical object or a person. Images may be two-dimensional (e. a photograph) or three dimensional (e. a statue). They are typicalls taken with such devices are known as x-ray photograph s or radiographs.
