Study Notes
Branches of Radiology
- Radiology consists of three major branches: Diagnostic Radiology, Radiation Therapy, and Nuclear Medicine.
Production of X-ray Beams
- High-speed electrons convert their energy into X-ray photons when they strike an atom.
- This process occurs in an X-ray unit.
Components of a Modern X-ray Unit
- Source of electrons (filament or cathode) to produce electrons.
- Evacuated space to accelerate the electrons.
- High positive potential to accelerate the negative electrons.
- Target or anode for the electrons to strike and produce X-ray photons.
Learn about the branches of radiology, including diagnostic radiology and radiation therapy. Understand how X-ray beams are produced and the components of a modern X-ray unit.
