Digital X-ray Detectors — Level 2
Flat panels, calibration, artefacts and wireless detectors
Part of the program: X-ray Service Engineer — full program (12 h) →
A calibration taken with the grid in place, a wireless link that gives up half a second too early, a battery that is not the original, a panel that was stood on — most 'dead detector' calls start with something that can be found in an hour if you know where to look. This course teaches the engineer who already services X-ray rooms to understand flat-panel detectors from the inside, keep them calibrated, read their artefacts, integrate them with generators and networks, and tell a real detector failure from everything that only looks like one.
The detector costs more than the rest of the room. Most detector calls are not detector faults.
- A flat-panel detector is often the most expensive single part in a radiography room, and it is the part most often blamed and replaced without proof.
- Wireless detectors added a battery, a radio link and an exposure-detection sensor to the image chain, and each of them produces faults that look like a broken panel.
- Calibration is run by whoever is in the room, under whatever conditions happen to be there, and a bad calibration is then applied faithfully to every patient image.
After the course you can
Curriculum
Identify the type of any digital X-ray detector on site - CR, indirect or direct DR, tethered or wireless - and name its main parts, what each part does and how each one typically fails.free
20 min02Handling and safety: drops, loads, liquids, climate and batteries
Set and check the handling, cleaning, climate and battery rules that keep a detector alive, and know exactly what to do after a drop, a spill or a battery problem.20 min03Integration: exposure synchronisation, links and the console
Explain how a detector and a generator agree on when to expose, find faults in wired and wireless links between detector, access point and console, and recognise timing faults that look like a dead detector.25 min04Calibration: offset, gain and defect maps done right
Know what each detector calibration corrects, set up the exact conditions the manufacturer requires, recognise when a calibration is due, and spot the image faults that a badly taken calibration writes into every patient image.25 min05Image quality and artefacts: detector, beam or software?
Recognise the common detector artefacts - lines, blocks, ghosting, grid patterns, noise, saturation and temperature effects - and decide with a few simple tests whether the cause is the detector, the generator and beam, the grid, or the software.25 min06Fault-finding and return to service
Fault-find the common detector complaints - not ready, lost connection, battery, blank image, calibration failure, cracked panel - in a fixed order, and return a detector to clinical use only after documented QC images and tests.25 min—Exam

The certificate
Pass the exam and get a certificate of course completion with your name, hours and score. Every certificate has a unique number and a public verification page, so an employer or a customer can check it in one click. It confirms completion of the course; it is not an educational document (diploma) and not a manufacturer authorisation.

Written by a service engineer working with medical equipment since 2014, including 6.5 years at GE Healthcare and service supervision at Mindray, together with the engineers of Service Engineer.
FAQ
Is this manufacturer training?
No. It is independent, vendor-neutral training. It does not replace the manufacturer's procedures and does not grant authorisation, service passwords, licences or access to service software.
Do I need Level 1 first?
X-ray Service — Level 1 is recommended: radiation safety, the image chain, DICOM and the basic idea of offset, gain and defect maps are assumed here and not repeated.
Will I learn to repair a detector panel?
No. A flat panel is a sealed, factory-calibrated assembly. The course teaches you to prove whether the panel is at fault, to fix everything around it, and to prepare a clean case for the manufacturer when it is.
Does it cover mammography and fluoroscopy detectors?
The principles are shared and examples from mammography and angiography are included. Modality-specific QC is covered in the Mammography Level 1 course and the manufacturer's documentation.
What does the certificate say?
Your name, the course, the hours, the date and your exam score, with a unique number and a public verification page.
Can my company buy seats for a team?
Yes: five seats and a progress overview for the manager.
