RAD 102 Chapter 1 (key points)

Radiation is utilized in medicine primarily for diagnostic imaging and treatment purposes. Common applications include X-rays, CT scans, and radiation therapy.

Historical Overview of Medicine

  • Medicine has evolved over centuries, starting from ancient practices to modern scientific approaches.

  • Key milestones include the establishment of anatomy through dissections in the Renaissance and advancements in microbiology in the 19th century.

Discovery of X-Rays

  • Wilhelm Conrad Röntgen discovered X-rays in 1895 while experimenting with cathode rays. He noticed a fluorescent glow from a nearby screen, leading to the realization of a new type of radiation capable of penetrating solid objects.

Terms Related to Radiologic Technology

  • Radiography: The use of X-rays to view the internal structure of an object.

  • Fluoroscopy: A technique that uses X-ray technology to obtain real-time moving images of internal structures.

  • CT (Computed Tomography): A diagnostic imaging technique that uses X-rays to create detailed images of the body.

  • MRI (Magnetic Resonance Imaging): A medical imaging technique that uses magnetic fields and radio waves to visualize organs and tissues.
