Across
- 3. Describes radiation that is emitted equally in all directions from a point source.
- 7. The electrical potential used to accelerate electrons in the x-ray tube. Higher kV = more penetrating x-rays.
- 11. The height of the wave, related to the intensity or strength of the wave.
- 16. A form of energy that travels in waves and includes visible light, x-rays, and radio waves. X-rays are a type of electromagnetic energy.
Down
- 1. The number of wave cycles per second (measured in Hertz). Higher frequency = higher energy.
- 2. When x-ray photons bounce off tissues in a new direction, potentially causing image blur or radiation exposure to staff.
- 4. Electromagnetic energy that is emitted or reflected in the form of waves or particles. X-rays are a form of radiant energy.
- 5. Refers to the energy or penetrating power of the x-ray beam (related to kVp).
- 6. The distance between two peaks of a wave. Shorter wavelengths = higher energy.
- 8. When x-ray photons pass through tissues without interaction, reaching the detector to form the image.
- 9. Refers to the number of x-ray photons produced (related to mAs).
- 10. When x-ray photons are stopped by tissues, transferring their energy and contributing to image contrast.
- 12. A packet of electromagnetic energy. X-rays are made of photons.
- 13. The ability to do work; it exists in various forms including potential and kinetic. In radiology, energy is used to generate x-rays.
- 14. Energy made available by the flow of electric charge through a conductor. It powers the x-ray machine.
- 15. Wilhelm Roentgen discovered x-rays in 1895. The unit “Roentgen” is also used to measure exposure to ionizing radiation.
