Question 1

Where can QC standards be found for monitoring a PACS system?

Accepted Answer

QC standards for monitoring a PACS system can be found in guidelines and recommendations provided by the American College of Radiology (ACR), the American Association of Physicists in Medicine (AAPM), and from the equipment vendors themselves. Each of these sources offers valuable information on maintaining the quality and performance of PACS systems.

Question 2

A device used to measure the luminescence of areas on the monitor is a

Accepted Answer

A photometer is the correct device used to measure the intensity of light, which includes the luminescence of areas on a monitor.

Question 3

What is most often the weakest link in the digital imaging chain?

Accepted Answer

The monitor is often considered the weakest link in the digital imaging chain because it is responsible for the visual representation of digital images, and its quality, resolution, and color accuracy can significantly affect the perceived quality of an image. Other components like image retrieval, processing speed, and data integrity, while important, do not directly impact the visual output as much as the monitor does.

Question 4

To make a valid performance measure in any QC activity,documentation must be

Accepted Answer

Keeping documentation up to date is crucial for a valid performance measure in any Quality Control (QC) activity. This ensures that all data reflects the current state of operations, allowing for accurate assessment and decision-making. The specific medium or person performing the documentation is less important than its accuracy and timeliness.

Question 5

How often should the luminescence of a monitor be checked?

Accepted Answer

The answer of How often should the luminescence of a...

Question 6

CQI tends to focus on ______ rather than the ______.

Accepted Answer

CQI (Continuous Quality Improvement) focuses on improving the process rather than blaming people, aiming to enhance overall performance by addressing the root causes of issues.

Question 7

"A plan for the systematic observation and assessment of the different aspects of a project,service,or facility to make certain that standards of quality are being met" is the definition of

Accepted Answer

This definition describes Quality Assurance (QA), which focuses on preventing defects by ensuring processes are followed to maintain quality standards.

Question 8

TJC accreditation is necessary for a hospital to

Accepted Answer

TJC accreditation is necessary for a hospital to hold certain licenses, obtain reimbursements from insurance companies, and receive malpractice insurance.

Question 9

The ultimate focus in health care is to improve ______ and provide ______ so that patients will want to return.

Accepted Answer

The ultimate focus in health care is to improve patient care and provide high-quality services to ensure patient satisfaction and encourage them to return for future health needs.

Question 10

Errors in equipment performance are usually detected by poor

Accepted Answer

Poor quality outcomes are often a clear indicator of errors in equipment performance, as they directly affect the final product or service quality. Equipment maintenance might influence performance but is not a direct method of detecting errors.

Question 11

Most health care institutions are accredited by

Accepted Answer

The Joint Commission (TJC) is a United States-based organization that accredits more than 22,000 health care organizations and programs. It is a widely recognized and respected accrediting body in the healthcare industry.

Question 12

Which of the following is not a QC activity that should be monitored in a PACS environment?

Accepted Answer

Repeat analysis is typically associated with quality control in imaging procedures, not specifically with PACS (Picture Archiving and Communication System) environments.

Question 13

Testing performed before newly installed or majorly repaired equipment can be accepted by the department is called ______ testing.

Accepted Answer

Acceptance testing is the process of verifying that newly installed or significantly repaired equipment meets the required specifications and is acceptable for operational use.

Question 14

Whereas QA/QC programs focus on ______ quality,CQI focuses on ______ the process.

Accepted Answer

QA/QC programs are designed to maintain quality by ensuring that products or services meet certain standards, while Continuous Quality Improvement (CQI) aims at improving the processes to enhance quality over time.

Question 15

Daily/monthly display monitor testing can be completed by

Accepted Answer

Daily and monthly display monitor testing can be completed by both technologists and physicists, as they have the necessary training and expertise to perform these tests accurately.

Question 16

"A comprehensive set of activities designed to monitor and maintain systems that produce a product" is the definition of

Accepted Answer

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

Question 17

Quality aspects to be evaluated in radiology include ______-centered characteristics.

Accepted Answer

Quality aspects in radiology encompass both people-centered characteristics, such as patient care and satisfaction, and product-centered characteristics, like the accuracy and clarity of diagnostic images.

Question 18

Testing that can catch problems before they may become radiographically apparent is called ______ maintenance.

Accepted Answer

The answer of Testing that can catch problems before they...

Question 19

Most QA activities produce ______ data.

Accepted Answer

QA (Quality Assurance) activities often produce quantitative data because they involve measurements, metrics, and statistical analysis to evaluate the quality of processes, products, or services. This data is numerical and can be used to make objective decisions.
