WHAT IS X-RAY technology?

The X-ray technology is one of the best-known diagnostic imaging procedures in medicine. Here are produced viewings from inside the body by using x-rays. X-ray procedures are fast and are used especially in bone, lung, breast and cardiac examinations. Various applications and organ-specific methods have prevailed:

  • Creating two-dimensional static images
  • Fluoroscopy over a longer period of observation of dynamic processes, such as in gastrointestinal examinations or surgery
  • Examination of vessels, usually with contrast agents 

BLACK AND WHITE IMAGES OF THE BODY’S INTERIOR

The X-ray technology is one of the best-known diagnostic imaging procedures in medicine.

An X-ray apparatus consists of an X-ray source and a receiving system, for example, a film cassette (analog X-ray) or a digital detector. The resulting two-dimensional images, the physician evaluates out of a light box or on the monitor. If 3D images needed, a CT scan is performed instead of an X-ray. When X is different for dense tissue, such as needed adipose tissues or bones, radiation of different wavelengths. One speaks also of soft and hard radiation. The softer radiation (low kV-values), the greater the proportion of radiation which is absorbed by the tissue. This means that the radiation exposure is higher, the softer the radiation. However, for certain tissue soft radiation is required in order to obtain a contrast imaging of tissue differences.
