Image Production II-Unit 1 filtration vocab

Front

What is a wedge filter used for?

Back

A wedge filter is a type of compensating filter used to even out densities, particularly in the foot or lower extremities.

Front

What does HVL stand for in radiology?

Back

HVL stands for Half-Value Layer, which is defined as the amount of absorbing material that will reduce the intensity of the primary beam to half its original value.

Front

What is a compensating filter?

Back

A compensating filter is used to even out unequal densities in radiographic imaging.

Front

What is a trough filter used for?

Back

A trough filter is a type of compensating filter that is used to even out densities, especially in the mediastinum.

Front

What does a filter do in radiology?

Back

A filter is any material designed to effectively absorb photons from the x-ray beam.

Front

What is the purpose of a K-edge filter?

Back

A K-edge filter is designed to selectively absorb certain energies of x-rays, improving image quality by reducing scatter.

Front

What is inherent filtration?

Back

Inherent filtration refers to the filtration that is a part of the x-ray tube and its housing, which naturally absorbs some x-rays.

Front

What is added filtration?

Back

Added filtration is the additional material placed in the path of the x-ray beam to absorb low-energy photons, improving image quality.

Front

How does a compensating filter differ from a regular filter?

Back

A compensating filter is specifically designed to even out varying tissue densities, while a regular filter may not have this specific purpose.

Front

What is the significance of the primary beam in radiology?

Back

The primary beam is the initial beam of x-rays produced by the x-ray tube, which is directed towards the patient.
