Listen to pronunciation. (SKA-ter RAY-dee-AY-shun) Radiation that spreads out in different directions from a radiation beam when the beam interacts with a substance, such as body tissue.

What causes radiation to scatter?

Scatter radiation is a type of secondary radiation that occurs when the beam intercepts an object, causing the X-rays to be scattered.

What is scattered radiation called?

They are protecting themselves from a particular form of radiation, called “scatter” or “secondary” radiation.

What is scatter radiation quizlet?

Scatter radiation. X-rays that travel in different direction after exiting patient body. Scatter radiation. Primarily a product of Compton interaction.

What are the two types of scatter radiation?

Three types of interactions occur when radiation is absorbed by matter: coherent scattering, Compton effect, and photoelectric effect. The result of either coherent scattering or the Compton effect is termed scatter radiation or simply scatter.

How can scatter radiation be controlled?

Control of side scatter can be achieved by moving objects in the room away from the detector, moving the x-ray tube to the center of the vault, or placing a collimator at the exit port, thus reducing the diverging radiation surrounding the central beam.

When does scattered radiation occur?

Scatter radiation is generated in the patient when an x-ray beam strikes the patient. The maximum scatter radiation occurs perpendicular to the x-ray beam. In other words, if the x-ray unit is above the patient, the highest scatter radiation at a set distance from the patient will be out to the side of the patient.

Where is scatter radiation found?

Scatter radiation is generated in the patient when an x-ray beam strikes the patient. The maximum scatter radiation occurs perpendicular to the x-ray beam. In other words, if the x-ray unit is above the patient, the highest scatter radiation at a set distance from the patient will be out to the side of the patient.

How does scatter radiation impact the exposure to the IR?

Scatter radiation is detrimental to radiographic quality because it adds unwanted exposure (fog) to the image without adding any patient information. Digital IRs are more sensitive to lower-energy levels of radiation such as scatter, which results in increased fog in the image.

How does scatter affect contrast?

Factors that Affect Radiographic Contrast: Scatter radiation will decrease the contrast of the radiograph; however, collimation can counterbalance this effect.
