X-ray final flashcard

Front

What are the 2 types of radiation produced when high speed electrons interact with matter?

Back

Bremsstrahlung and characteristic radiation.

Front

What does filtration do to the x-ray beam?

Back

Filtration reduces x-ray beam intensity but increases the average energy of the photons.

Front

What type of filtration exists due to how it is made?

Back

Inherent filtration.

Front

What is the composition of the x-ray beam?

Back

The x-ray beam is made up of photons.

Front

What are the 3 things that can happen to x-ray photons when they interact with the human body?

Back

Absorption, scatter, and transmission.

Front

Define bremsstrahlung radiation.

Back

Bremsstrahlung radiation is produced when high-speed electrons are decelerated or deflected by the electric field of atomic nuclei.

Front

Define characteristic radiation.

Back

Characteristic radiation is produced when an inner-shell electron is ejected from an atom, and an outer-shell electron falls into the lower energy state, releasing energy in the form of an x-ray photon.

Front

What is inherent filtration in x-ray machines?

Back

Inherent filtration refers to the filtration that is built into the x-ray tube itself, typically from the glass or metal envelope.

Front

What is the purpose of filtration in x-ray imaging?

Back

The purpose of filtration is to remove low-energy photons from the x-ray beam, which do not contribute to image formation and increase patient dose.

Front

What is the difference between absorption and transmission of x-ray photons?

Back

Absorption occurs when x-ray photons are completely absorbed by the tissue, while transmission occurs when x-ray photons pass through the tissue without interaction.
