Question 1

Improper cleaning of the CRT can lead to:

Accepted Answer

Improper cleaning of the CRT can lead to both streaks and smears, and if harsh chemicals are used, it can also cause illnesses. Therefore, option D is the correct choice.

Question 2

When cleaning imaging plates, which of the following should not be used?

Accepted Answer

Mild abrasive should not be used when cleaning imaging plates as it can damage the delicate emulsion layer on the plate. The best choice would be B, lint-free cloth, as it is gentle and won't scratch or damage the plate. Additionally, a cleaning solution specifically designed for imaging plates can be used to help remove any stubborn debris or stains. A camel hair brush can also be used, but it should be soft and gentle to avoid scratching the plate.

Question 3

The safest procedure for erasing cassettes is to erase them:

Accepted Answer

The safest procedure for erasing cassettes is to erase them just before use. This ensures that any confidential or sensitive information is not accidentally recorded and can be securely erased immediately after use. Erasing twice a day or twice a week may not be necessary or efficient, and waiting for 24 hours can leave enough time for someone to accidentally record over the sensitive information.

Question 4

A comprehensive set of activities designed to monitor and maintain a piece of equipment is known as:

Accepted Answer

The answer of A comprehensive set of activities designed to...

Question 5

Which of the following is not a monthly QC procedure for digital projection imaging systems?

Accepted Answer

The answer of Which of the following is not a...

Question 6

Which one of the following is used to cool the reader?

Accepted Answer

Air is commonly used to cool electronic devices such as readers. It is a cost-effective and efficient method of cooling compared to water or oil cooling systems, which can be more complicated to implement and maintain. Laser is not used for cooling purposes.

Question 7

Image orientation can be difficult because of a lack of ______ the cassette.

Accepted Answer

The answer of Image orientation can be difficult because of...

Question 8

On a weekly basis, a designated QC technologist may perform all of the following tests except:

Accepted Answer

Cleaning air intakes on the image plate reader does not fall under the usual responsibilities of a QC technologist.

Question 9

If the hinges of a cassette are broken, they can be fixed by the:

Accepted Answer

Broken hinges on a cassette are a mechanical issue and require a service personnel to fix them. Technologists, radiologists, and radiation physicists do not typically handle mechanical repairs on equipment.

Question 10

Frequent and consistent oversight of digital equipment is necessary to avoid:

Accepted Answer

Frequent and consistent oversight of digital equipment is necessary to avoid unnecessary patient exposure, as there is a risk of increased radiation exposure if the equipment is not properly calibrated and maintained. This also ensures that the equipment is functioning properly and producing high-quality images, which is important for accurate diagnoses and optimal patient care. QC is a part of this oversight process, but it is not the only factor to consider. Increased cost may also be a consequence of not properly maintaining the equipment, but it is not the primary concern.

Question 11

"The overall efficiency and effectiveness of imaging systems evaluated beyond the mechanics of producing radiographic images" is a definition of:

Accepted Answer

The answer of "The overall efficiency and effectiveness of imaging...

Question 12

Imaging plates may be disposed of by:

Accepted Answer

Imaging plates contain small amounts of radioactive material and should be disposed of properly to prevent any harm to the environment or individuals. The best way to dispose of imaging plates is by using a licensed disposal company that specializes in the safe handling and disposal of radioactive materials. They can ensure that the plates are disposed of in compliance with local and federal regulations to protect public health and the environment. Simply placing them in the trash or storing them in barium sulfate is not an appropriate method of disposal. Sending them to the EPA is also not necessary, as they do not handle disposal of radioactive materials.

Question 13

Another name for quality management is:

Accepted Answer

The answer of Another name for quality management is:
...

Question 14

Which of the following is not a weekly procedure?

Accepted Answer

The answer of Which of the following is not a...

Question 15

Major artifacts should be noted and reported:

Accepted Answer

Major artifacts should be noted and reported immediately to ensure prompt action and prevent further damage or issues. Waiting to report them could result in serious consequences for the artifact or the project as a whole.

Question 16

Image acquisition is tested through the use of:

Accepted Answer

Phantoms are artificial objects designed to simulate the characteristics of human tissues and organs, and are commonly used to test and evaluate imaging equipment and techniques. They can be designed to mimic different parts of the body and different conditions, allowing researchers and technicians to evaluate image quality and accuracy under a variety of scenarios.

Question 17

If the printer glass becomes obstructed by dirt or fingerprints, artifacts on the printed image can be interpreted as:

Accepted Answer

The answer of If the printer glass becomes obstructed by...

Question 18

The purpose of a personal repeat rate log is to:

Accepted Answer

The answer of The purpose of a personal repeat rate...

Question 19

General system inspection includes all of the following except:

Accepted Answer

General system inspection in the context of radiology and imaging systems typically includes checking the physical condition and cleanliness of equipment, such as cassettes, and ensuring that mechanical parts like hinges and latches are in good working order. Erasure of imaging plates is also a routine part of maintaining digital imaging systems to ensure image quality. However, cleaning the CRT (Cathode Ray Tube) is not a standard part of general system inspection for imaging systems, as CRTs are more relevant to older display technologies and not directly related to the maintenance of imaging quality or system functionality in modern digital imaging systems.

Question 20

Positioning errors may be the cause of incorrect processing due to mistakes in:

Accepted Answer

Positioning errors can be caused by mistakes in part-to-plate position, collimation, and alignment. Therefore, all of the above choices are the best options.
