Question 1

Which of the following projections will always require a compensating filter to demonstrate all of the anatomy on one image?
1)AP shoulder
2)Lateral hip
3)Lateral C7-T1
A) 1 and 2
B) 2 and 3
C) 1 and 3
D) 1, 2, and 3

Accepted Answer

A lateral hip projection may require a compensating filter to ensure the femoral head and neck visualized on the same image as the greater trochanters. A lateral C7-T1 projection may also require a compensating filter to demonstrate the entire cervical spine on one image. However, an AP shoulder projection typically does not require a compensating filter.

Question 2

Which of the following is required to maintain an even radiographic density on body parts that have significant variations in tissue density?
A) Increase the kVp.
B) Increase the mA.
C) Use a compensating filter.
D) Use a compression device.

Accepted Answer

Using a compensating filter is the best choice as it can help to even out the radiographic density on body parts that have significant variations in tissue density. Compensating filters are designed to reduce the amount of radiation that passes through thicker parts of the body, while allowing more radiation to pass through thinner parts. This helps to produce a more even density on the final image. Increasing the kVp or mA may not provide an even density and may result in decreased image quality. Using a compression device may also help to even out density in some cases, but it is not always feasible or appropriate.

Question 3

Where are most compensating filters placed?
A) Under the patient
B) Directly on the patient
C) Between the x-ray tube and skin surface
D) Between the x-ray tube and collimator

Accepted Answer

Most compensating filters are placed between the x-ray tube and skin surface to equalize the radiation dose for structures of varying densities.

Question 4

The major advantage of using collimator-mounted compensating filters is:
A) ease of use.
B) can be used for different body areas.
C) provide increased contrast and detail.
D) reduction in radiation exposure to the patient.

Accepted Answer

Collimator-mounted compensating filters are designed to reduce radiation exposure to the patient by reducing the amount of scattered radiation. This makes them useful for achieving a more uniform radiation dose throughout the body while minimizing the overall radiation dose.

Question 5

For which projection would two double-wedge filters be used?
A) AP shoulder
B) Lateral hip
C) AP spine for scoliosis
D) Lateral spine for scoliosis

Accepted Answer

Two double-wedge filters are typically used for the lateral spine projection for scoliosis imaging to reduce radiation dose to sensitive organs such as the thyroid and mammary glands. The other projections listed do not typically require the use of double-wedge filters.

Question 6

A special-design Ferlic filter would provide an even image density for which of the following projections?
1)AP thoracic spine
2)Lateral C7-T1 (swimmer's method)
3)Lateral hip (Danelius-Miller method)
A) 1 and 2
B) 2 and 3
C) 1 and 3
D) 1, 2, and 3

Accepted Answer

The answer of A special-design Ferlic filter would provide an...

Question 7

The Boomerang filter would provide an even image density for which body area?
A) Hip
B) Chest
C) Shoulder
D) C7-T1 region

Accepted Answer

The answer of The Boomerang filter would provide an even...

Question 8

Which of the following would be considered advantages in using anatomic compensating filters?
1)Reduces radiation exposure to the patient
2)Provides an even image density
3)Increases image contrast and detail
A) 1 and 2
B) 2 and 3
C) 1 and 3
D) 1, 2, and 3

Accepted Answer

Anatomic compensating filters reduce radiation exposure to the patient by selectively attenuating the x-ray beam in areas of the body that are thicker, such as the abdomen and pelvis. This helps to provide an even image density and increases image contrast and detail.

Question 9

A trough filter would be used for a:
A) lateral hip.
B) AP shoulder.
C) PA chest.
D) AP thoracic spine.

Accepted Answer

A trough filter is used for a PA chest to even out the exposure between the denser mediastinum and the less dense lungs.

Question 10

A commonly performed projection that is significantly improved with the use of a compensating filter is the AP:
A) hand.
B) skull.
C) leg.
D) thoracic spine.

Accepted Answer

A compensating filter is often used in thoracic spine AP projections to even out the density differences between the thicker and thinner parts of the body, improving image quality.

Question 11

The most common materials used in the manufacture of compensating filters are:
1)copper.
2)aluminum.
3)high-density plastics.
A) 1 and 2
B) 2 and 3
C) 1 and 3
D) 1, 2, and 3

Accepted Answer

Compensating filters are typically made from materials like aluminum and high-density plastics due to their ability to shape and attenuate radiation effectively. Copper is not commonly used for this purpose.

Question 12

A wedge filter would be ideal for which of the following projections?
A) AP chest
B) AP thoracic spine
C) Lateral C7-T1
D) Lateral hip

Accepted Answer

The answer of A wedge filter would be ideal for...

Question 13

The simplest and most common shape of compensating filter is the:
A) wedge.
B) trough.
C) double-wedge.
D) Boomerang.

Accepted Answer

The wedge-shaped compensating filter is the simplest and most commonly used type of filter. It is designed to compensate for the natural variation in the thickness of body tissues, which can cause variations in the amount of radiation that reaches the image receptor. The filter is thicker on the side that the beam enters and thinner on the side that the beam exits, which helps to equalize the radiation dose across the entire image. Trough and double-wedge filters are also used, but they are more complex and typically reserved for specific applications. The boomerang filter is not a real type of compensating filter.

Question 14

Which of the following will provide maximum patient safety when using compensating filters?
A) Use two hands to mount a collimator filter.
B) Use two hands to position a contact filter.
C) Use a low-kVp exposure technique.
D) Use a high-mA exposure technique.

Accepted Answer

Use two hands to mount a collimator filter provides maximum patient safety when using compensating filters.
