CT Service — Level 1
Safety, calibration and preventive maintenance
Air conditioning, dirty filters, a skipped air calibration, a slip ring nobody cleaned — most CT failures start with something cheap that nobody checked. This course teaches the engineer who maintains a CT scanner to keep it safe, calibrated and running.
The tube is the most expensive part. Most CT downtime starts somewhere cheaper.
- A CT scanner that stops loses a full day of patients, and most stoppages start with something cheap: a hot room, dusty filters, a skipped calibration, worn slip ring brushes.
- The tube costs as much as a car, and how it is warmed up, loaded and cooled decides whether it lasts its expected life or fails early.
- Manufacturer courses are expensive, model-specific and often closed to independent engineers; the safety and maintenance basics every CT shares are rarely taught on their own.
After the course you can
Curriculum
Place any CT complaint on the chain from mains to PACS, say whether the faulty part sits on the stationary side or on the rotor, and decide whether the cause lies before or after the patient.free
20 min02The power chain and high voltage: isolate, discharge, verify
Follow CT power from the supply to the X-ray tube, check supply quality correctly, and make a CT gantry safe for work by isolation, lock-out, waiting for stored energy to discharge and verifying absence of voltage.22 min03Radiation safety for the CT engineer
Work on a CT scanner so that your own radiation dose stays as low as reasonably achievable: never in the room during exposure, interlocks and warning lights checked and never defeated, personal dosimeter worn, and shielding problems reported.22 min04The X-ray tube: warm-up, conditioning and heat
Explain why a CT tube must be warmed up and conditioned, read cooling waits correctly, track tube counters and error logs at every visit, and recognise the combined signs that a tube is approaching end of life.22 min05Operator calibrations: air calibration and the daily phantom check
Know what the air calibration and the daily phantom check actually correct and measure, run or review them correctly, and recognise the point at which calibration stops being the answer and a detector or service-level fault begins.20 min06Cooling: three loops in series
Trace the heat of a CT scanner from the anode to the outside air through three loops, check and clean each loop on a maintenance visit, and tell a genuine cooling fault from a room that cannot carry the heat or a workload that exceeds the design.20 min07Planned maintenance by checklist
Carry out a CT planned maintenance visit in a safe, repeatable order - preparation, safe access, gantry mechanics and slip ring, table and lasers, cables and interlocks, console and backups, then return to service - recording as-found and as-left condition at every step.25 min08Image quality control with the ACR phantom, and the maintenance report
Use an independent phantom such as the ACR CT accreditation phantom to check CT number accuracy, noise, uniformity and low contrast against a baseline, and write a maintenance report with as-found and as-left results, a tube log, cooling remarks and a clear statement of scope and fitness for use.25 min—Exam

FAQ
Is this manufacturer training?
No. It is independent, vendor-neutral training. It does not replace the manufacturer's procedures or grant authorisation or access to service software.
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.
