Study Notes
Introduction to Radiology
- Radiology involves studying x-rays and techniques for producing radiographic images.
- X-Radiation is high-energy radiation created by electron collisions with tungsten targets.
Development of X-Ray Technology
- Initially required long exposure times; improvements allowed for shorter times.
- Both sides of film are now coated with emulsion for enhanced quality.
Dental X-Ray Film History
- Early films were glass plates wrapped in black paper and rubber; Kodak introduced machine-wrapped film packets in 1919.
- In initial stages, only one side had emulsion coating, but advancements improved overall film quality.
Applications of Dental Imaging
- Detects lesions, diseases, and conditions of teeth not visible clinically.
- Confirms suspected diseases and localizes lesions or foreign objects.
- Provides critical information during dental procedures and evaluates growth and development.
- Observes changes due to caries, periodontal issues, and trauma.
Radiation Safety Goal
- Aim to obtain high-quality radiographs with the lowest possible radiation exposure.
- Adhere to the ALARA principle (As Low As Reasonably Achievable) to minimize unnecessary radiation doses.
Historical Milestones in Radiology
- Wilhelm Conrad Roentgen discovered x-rays in 1895 and received the first Nobel Prize in Physics in 1901.
- Initially named "Roentgen Rays," x-rays were later termed "x-rays" (with "x" denoting the unknown).
- Digital dental radiography was introduced in 1987, replacing film and requiring less radiation.
Overview of Atomic Structure and Radiation
- Atoms are electrically neutral, consisting of protons and electrons.
- Ionization occurs when atoms gain or lose electrons, leading to the formation of ion pairs.
- Two types of ionizing radiation include particulate and electromagnetic radiation.
- Electromagnetic radiation involves wave-like energy movement, defined by wavelength and frequency.
Properties of X-Rays
- X-rays are invisible, carry no mass, and have no charge.
- They travel at the speed of light in straight lines and cannot be focused to a point.
- X-rays can penetrate various materials, are absorbed by matter, and can produce images when interacting with receptors.
- Cause biological changes to living cells, underlining the importance of safety in their use.
X-Ray Tube and Components
- The Ray Tubehead houses the x-ray tube, made from tightly sealed metal.
- Insulating oil surrounds the x-ray tube to absorb heat generated during x-ray production.
