16. Quality assurance and quality control Flashcards
what is quality assurance
what is included in this
systems and procedures for assuring quality patient care.
quality assessment, administrative aspects of patient care and continuing education and quality control
what is quality control
a component of QA
monitoring the variables that affect the image quality and radiation dose
technical part of equipment performance
what are the 3 objectives of the QA programme
maintain optimal quality images
reduce unnecessary radiation exposure to patient and staff
to be cost efficient
what are the 5 factors of what MIT are responsible for in QA
ensuring appropriate protocol and exposure technique is used for the requested examination
perform/interpret QC test and records for QC file
perform daily, monthly, quarterly QC tests
report faults
administration: control charts/records
what are the 5 factors of what MIT are responsible for in QC
preventative maintenance = checking equipment
training of staff = standardize QA procedures
an integral part of QA
measurable actions to keep high quality images within specified limits
what must QC data be

what are 3 examples of data recording in QC
control charts
room logs/records
maintenance logs/records
what are the 4 things that are part of the daily QC visual checks
equipment = cables, tube housing and light box
detectors = artifacts
what are the 2 things that are a part of the daily QC tests
visual checks
machine warm up
what are the 6 things for weekly QC checks
visual inspection/cleaning
plate erasure
visual inspection and cleaning of reader and printing components
CR reader detector dose/EI monitoring
CR reader uniformity
printer test
what is a SMPTE test pattern used for
help you determine whether the contrast and brightness settings of your monitor are acceptable
what are rejected images
an image that needs to be re-done
what is a RIS system
what are the 3 things that are included in it
information system
patient info, examinations scheduled, radiologists reports
what are PACS
what 4 things does it do
used for storage, retrieval, management and distribution of medical images
what are 4 reasons for rejected/repeat analysis
