Study Notes
X-ray Properties
- X-rays are invisible, massless, and carry no charge.
- X-rays travel at the speed of light in straight lines and can be deflected or scattered.
- X-rays have short wavelengths and high frequencies, which allow them to penetrate matter.
- The degree of penetration depends on the composition of the substance.
- X-rays cause ionization and fluorescence in materials they interact with.
- X-rays are absorbed by matter depending on the atomic structure and wavelength of the x-ray.
- X-rays are used to create images on receptors and can cause biological changes in living cells.
X-ray Tubehead Components
- The metal housing protects the x-ray tube and its components.
- Insulating oil prevents overheating by absorbing heat.
- The tubehead seal seals the oil and filters the x-ray beam.
- The x-ray tube is the heart of the x-ray system and consists of the following:
- Cathode: Includes a tungsten filament that produces electrons when heated.
- Anode: Has a tungsten target that converts electrons into x-ray photons, embedded in a copper stem that dissipates heat.
Leaded-Glass Housing
- It is a leaded-glass vacuum tube that prevents x-rays from escaping in all directions.
- A window in the tube allows the x-ray beam to exit and is directed toward the aluminum disks, lead collimator, and PID.
Cathode
- It is the negative electrode and consists of a tungsten filament in a molybdenum cup.
- Its purpose is to provide electrons necessary for x-ray production.
- Electrons are accelerated towards the anode.
Anode
- It is the positive electrode and consists of a tungsten plate embedded in a copper rod.
- Its purpose is to convert electrons into x-ray photons.
