LESSON 1
Introduction to Radiology. Technology of radiological diagnostic methods and
its organization. Discovery, nature and properties of X rays.
Radiology is the study of images of the human body. A Radiologist is a
physician who has become a specialist in Radiology - a doctor who has taken
additional training in the interpretation of medical images and the performance of
imaging procedures.
Although Radiology began with the use of X-Rays and large flat sheets of
photographic films, the modern Radiologist now has a variety of tools for "taking
pictures" of living patients. Many of these newer tools create an image with a
computer (CT - computed tomography) and some do not use any X-Rays, nor
radiation of any kind - such as MRI (Magnetic Resonance Imaging) and US
(Ultrasound).
Radiologists must have a great understanding of Anatomy, Pathology, and
Physiology in order to make accurate diagnoses.
HISTORY OF RADIOLOGY.
German physicist Wilhelm Roentgen discovered Xrays and received the
Nobel prize for physics in 1901. His achievement heralded the age of modern
physics and transformed medical practice.
In 1895 Roentgen began experiments at the University of Wartburg with an
electric current flow in a partially evacuated glass tube (known as a cathode-ray
tube). He noticed that, whenever the tube was in operation, a piece of barium
platinocyanide in line with it gave off light. Roentgen theorized that the interaction
of electrons striking the tube's glass wall formed an unknown radiation that caused
the fluorescence. He called the mysterious phenomenon X radiation, or X rays.
Further experiments revealed that X radiation produces an image on photographic
