Equipment Operation and Quality Assurance on the ARRT radiography exam
Equipment Operation and Quality Assurance has 25 of the 200 scored questions in the Image Production category. It covers the x-ray machine from the generator to the display monitor: how the tube and generator work, how digital detectors and fluoroscopic units capture images, how raw data become a displayed image, how images move through PACS, and how equipment is tested.

What Equipment Operation and Quality Assurance questions test
- Generators and rectification: transformers, single-phase, three-phase and high-frequency generators, ripple and tube loading
- X-ray tube: filament and focusing cup, rotating anode and induction motor, target materials, line focus principle and filtration
- AEC hardware, back-up timer and minimum response time, and manual exposure controls
- Digital detectors: direct conversion (amorphous selenium) and indirect conversion (scintillator with amorphous silicon, CCD or CMOS); fluoroscopic image intensifiers and flat panels
- Image processing and display: ADC, histograms, rescaling and flat-fielding, LUTs, window level and width, edge enhancement, smoothing, monitor viewing conditions, PACS, DICOM, HIS/RIS and downtime procedures
- Quality control: light field to radiation field alignment, detector calibration, monitor QC and lead apron testing

Free Equipment and QC drillHow to study it
- Draw the x-ray tube once from memory, cathode to anode, and label each part with its job.
- Learn the processing chain in order: raw data, corrections, histogram analysis, LUT, then post-processing.
- Remember the collimator rule: light and radiation fields must align within 2% of the SID.
- Take the equipment and QC drill until you score 80% or better.
Common questions
What equipment topics are new in 2027?
The specifications effective March 1, 2027 add virtual grids, image security and confidentiality and teleradiology, and remove computed radiography and compensating filters.
Are window level and window width on the ARRT exam?
Yes. Post-processing of brightness and contrast is in the outline: window level adjusts brightness and window width adjusts contrast.
