X-Ray equipment
• X-rays were discovered by the German physicist Wilhelm Konrad
Röntgen in November 1895.
• He called the ‘new kind of ray’ or X-rays, X for the unknown. With the
new rays, he could make a photograph of his wife’s hand—showing t
bones and her wedding ring.
• Soon afterwards, their usefulness to visualize the internal anatomy o
humans was established.
• Today, imaging with X-rays is perhaps the most commonly used
diagnostic tool with the medical profession, and the techniques from
simple chest radiography to a digital subtraction angiography or
computer tomography depend on the use of X-rays.

Basis of diagnostic radiology
A radiological examination is one of the most important diagnostic a
available in the medical practice.
It is based on the fact that various anatomical structures of the body
have different densities for the X-rays.
When X-rays from a point source penetrate a section of the body, th
Internal body structures absorb varying amount of the radiation.
The radiation that leaves the body has a spatial intensity variation, i.
an image of the internal structure of the body.
