X-ray Photon Interactions Flashcard 5

Front

What is the purpose of shielding in radiation control?

Back

To shield yourself from the source of radiation.

Front

What is the role of transmission in x-ray interaction with the body?

Back

It penetrates through the body to interact with the film/image receptor.

Front

What is the main cause of scatter radiation?

Back

Compton Scattering.

Front

What happens to x-ray photons during the photoelectric effect?

Back

They are absorbed by the tissues and do not contribute to image quality.

Front

What happens to the electron in the Photoelectric Effect?

Back

It absorbs all the energy from a photon.

Front

Define Compton Scattering.

Back

A phenomenon where x-ray photons collide with electrons, resulting in a change in direction and energy of the photons.

Front

What is the Photoelectric Effect?

Back

The process by which x-ray photons are completely absorbed by matter, transferring all their energy to an electron.

Front

Explain the significance of transmission in radiography.

Back

Transmission is crucial as it allows x-ray photons to pass through the body and create an image on the film or digital receptor.

Front

What is the effect of scatter radiation on image quality?

Back

Scatter radiation can cause fogging on the radiograph, reducing image clarity.

Front

How does the energy of an x-ray photon affect its interaction with matter?

Back

Higher energy photons are more likely to penetrate matter, while lower energy photons are more likely to be absorbed or scattered.
