Medical display calibration and QA for diagnostic monitors
A diagnostic display drifts as it ages. We calibrate reporting and clinical review monitors to the DICOM Grayscale Standard Display Function, run acceptance and scheduled QA tests, and keep the records your accreditation and radiologists rely on.
From the first measurement on install to the replacement recommendation at end of life.
Acceptance testing
When a display is installed, moved or repaired: luminance, uniformity, GSDF conformance and visual test patterns (AAPM TG18 and IEC 62563 part 1 style tests), recorded as the baseline.
DICOM GSDF calibration
Calibration with the display's integrated front sensor or an external photometer, set to the luminance targets your practice and its standards require.
Scheduled QA
A cadence that layers continuous automated monitoring (where the display and its QA software support it), periodic measured tests and quick visual checks by staff. We set it up, watch it and act on failures.
Reading room environment
We check reading room lighting and placement and recommend changes where they affect image presentation.
Records for accreditation
Test results, calibration history and asset lifecycle in one place, ready for accreditation and internal audit. Reference points: the current RANZCR standards of practice and the Diagnostic Imaging Accreditation Scheme (DIAS) in Australia, and IANZ in New Zealand (see the New Zealand monitor rules guide).
Lifecycle and replacement
When a display can no longer hold its calibration targets, we recommend a like for like or better replacement from the LG, EIZO and Barco ranges, and plan the swap around reporting sessions.
Find out if your reporting displays still conform
Book a display QA check: tell us which displays you run and how they are tested today, and we will tell you what to measure next and what the records should show.
One checks the screen a study is read on. The other checks the report written from it. Practices often need both.
Display calibration and QA (this service)
Measures luminance, uniformity and GSDF conformance on each display.
Keeps calibration history and test results for accreditation.
Report quality assurance
ClariRad QA is Trucell built software that checks radiology reports for critical errors as they are written.
It does not measure or calibrate displays, and display QA does not check reports.
Medical display calibration FAQ
What radiology practice managers and radiologists ask about display calibration and QA.
How often should diagnostic displays be calibrated?
It depends on the display, its QA software and your practice's standards. Most programs combine continuous automated monitoring, periodic measured tests and frequent visual checks. Check the current RANZCR standards for the cadence that applies to you, and we will set the schedule to match.
What is DICOM GSDF calibration?
The DICOM Grayscale Standard Display Function defines how image values map to displayed brightness so grey steps look perceptually even. Calibrating to it makes a study look consistent across conformant displays.
Do clinical review displays need QA too?
Yes, though the expectation is lighter than for primary diagnostic displays. They still need a defined target and periodic checks.
Can you calibrate home reporting monitors?
Yes. We set up and calibrate home reporting displays and include them in remote QA monitoring where the display supports it.
Do you only calibrate displays you sold?
No. We calibrate and QA existing LG, EIZO and Barco fleets, and report honestly when a display is past the point where it can hold its targets.
Which standards do you test against?
We use test methods from the AAPM TG18 report and the IEC 62563 series, and align targets with the current RANZCR standards of practice and your accreditation body's requirements.
