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 is scattered radiation caused by?

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

How does scatter radiation work?

What is Scatter Radiation? As defined by the National Cancer Institute, scatter radiation is secondary radiation that spreads in different directions from a beam when that beam interacts with any substance, such as body tissue, a wall, or a table.

What is scattered radiation How is it reduced?

To reduce the scattered radiation, possible methods are smaller fields-of-view (FOV), larger air gap between object and detector, and the use of an anti-scatter grid. Large air gaps may give rise to geometrical un-sharpness, which must be kept minimal for high-resolution detectors.

What are the benefits of scattered radiation?

In nondestructive testing, it offers three advantages. (i)It permits to place both the radiation source and the detector on the same side of the object. (ii)It has also greater sensitivity to low-density materials such as gases. (iii)Finally, it allows direct spatial definition with high-contrast resolution.

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 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.

How does scatter radiation can 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.

How does scatter radiation affect image?

Radiographic Effect of Scatter Radiation Fog is unwanted exposure to the image. It does not strike the IR in a pattern that represents the subject, and it contributes nothing of value to the image. This fog produces an overall increase in radiographic density.

What is scatter radiation example?

Radiation that spreads out in different directions from a radiation beam when the beam interacts with a substance, such as body tissue. For example, during x-ray mammography, very small amounts of radiation may be scattered to areas away from the breast, such as the head and neck, sternum, and thyroid gland.
