prac qs Flashcards
Two areas of activity designed to ensure the best possible diagnosis at an acceptable patient radiation dose and with minimum cost. Both programs rely heavily on proper recordkeeping.
- Quality Assurance and Quality Control
According to _____, registrants and licensees shall establish a comprehensive QA program for medical exposures with the participation of appropriate qualified experts in radiophysics taking into account the principles established by the WHO.
International Basic Safety Standards (IBSS) in 2014
Or Radiation Protection and Safety of Radiation Source: IBSS
Healthcare organizations often adopt formal, structured QA models. The Joint Commission (TJC) promotes _____
“The Ten-Step Monitoring and Evaluation Process”
It is the organized efforts of a facility to ensure the high standard of quality of its product.
Quality Assurance
In QA, It requires attention from the imaging team, but they are principally the responsibility of the ___
radiologist and the imaging service management.
It is designed to ensure that the radiologist is provided with an optimal image produced through good imaging system performance and resulting in minimal patient radiation dose. (QA or QC)
QC
Was the report of diagnosis promptly prepared, distributed, and filed for subsequent evaluation? (Qa or Qc)
QA
An acceptable QC program consists of three steps:
Acceptance Testing
Routine Performance Monitoring
Maintenance
In radiology, it is an organized effort by the staff operating a facility to ensure that the diagnostic images produced are of sufficiently high quality so that they consistently provide adequate diagnostic information at the lowest possible cost and with the least possible exposure of the patient to radiation (World Health Organization, 1982).
Quality Assurance
requires team effort but it is principally the responsibility of the medical physicist. QA or QC
QC
deals with instrumentation and equipment. QA or QC
QC
A program of ___ monitors proper scheduling, reception, and preparation. QA or QC
QA
It begins with the imaging systems used to produce the image and continues with the routine evaluation of image-processing facilities. QA or QC
QC
It deals with people. QA or QC
QA
It is performed at the installation of the equipment. It is to check the performance before clinical use, utilizing a pass or fail acceptability criteria
Acceptance Testing
Examples of Routine Performance Testing
Different timetables (daily, monthly, annually) can be used depending on the nature of the test.
Safety system tests (emergency stop)
X-ray tube performance (nominal kV)
Image quality tests (resolution, artifacts)
Display performance
Dosimetry
System inspection , physical inspection, secondary erasure of IP are done _____ by _____
Daily, Radtech
involves image interpretation. QA or QC
QA
concludes with a dedicated analysis of each image to identify deficiencies and artifacts (along with their causes) and to minimize reexaminations. QA or QC
QC
____provides a baseline values for image quality and radiation dose (compared with future periodic tests)
Commissioning testing
maintenance is a planned program of parts replacement at regular intervals and usually makes repair unnecessary.
preventive
Verification of displayed image, phantom image quality control testing (image quality and artifats) is done _____ by _____
weekly, radtech
maintenance is due to a failure in the system that necessitates repair.
non-scheduled
outcome analysis. QA or QC
QA
Evaluate image quality and pt dose, acceptance tests to re-eastablish baseline value are done ____by___
SEMI-ANNUALLY/ANNUALLY, Medical Physicist
maintenance is performed on a routine basis
scheduled
Inspect and clean IR, review image rejection rate, and QC review of “Out of tolerance” issues are done _____ by _____
monthly, radtech
Review of PT exposure trends, retake activity, QC records, service history are done ____by___
semiannually/annually, medical physicist
Adherence to policies and procedures. QA or QC
QA
Periodic testing and maintenance of performance throughout its lifespan. QA or QC

What are the components of quality management programs?
Equipment quality control
Administrative responsibilities
Risk management
Radiation safety program
ability to identify potential risk to patients, employees, and visitors at the healthcare institution (ex. nosocomial infections)
risk management
involves evaluation of equipment performance to ensure proper image quality, as well as patient and operator safety.
equipment quality control
involves the establishment of various processes to accomplish the specific departmental task. It includes: Procedure manuals, Data collections, Scheduling, and routing of patients, Education of personnel, Equipment acquisition, and Communication with other department
administrative responsibilities
cardinal principles
time
distance
shielding
ensure that patient exposure is kept as low as reasonably achievable (ALARA). Medical staff, department personnel, and member of the general public are also protected from overexposure to ionizing radiation.
