On-site CT diagnosis, repair, and calibration. Tube, cooling, detector, and software problems on all major brands, including nights and weekends.
Call 1-855-409-2885 | Request Service
VectoRay Medical repairs CT scanners on-site for hospitals, clinics, and imaging centers throughout California and surrounding states. We diagnose tube, cooling, detector, gantry, and software problems, make the repair, run the calibrations, and verify performance before the scanner returns to patient use.
Is your CT scanner down right now? Do this first
- Stop scanning and secure patient safety per your procedures.
- Record what happened: error codes, arc or cooling alarms, scan abort messages, and when it began.
- Don’t push through repeated arc or cooling errors. Repeated attempts can stress the tube and make the problem worse.
- If you see oil leaking from the tube housing, treat it as an emergency. Stop and call right away.
- Don’t open covers. CT systems involve high voltage and a rotating gantry.
- Have the make, model, serial number, and your last service report ready.
- Call us at 1-855-409-2885.
CT systems we repair
We service CT scanners from major manufacturers, including GE, Siemens, Philips, and Canon, for hospitals, outpatient imaging centers, and clinics. Call with your make, model, and software version to confirm coverage.
Common CT problems we diagnose and repair
| What you’re seeing | What it can indicate |
|---|---|
| Arc errors, failed tube warm-ups, or scans aborting mid-pass | Tube or high-voltage problems |
| A bearing whine, hum, or rumble as the anode spins up | Tube bearing wear |
| Cooling alarms, long cooldown delays, or overheating | Heat exchanger, coolant, filter, or airflow problems |
| Ring, streak, or band artifacts, or failed air and water calibrations | Detector or data-acquisition drift, tube problems, or gantry issues |
| Gantry rotation, slip ring, or table motion faults | Mechanical wear |
| Console freezes, reboots, reconstruction failures, or images not reaching PACS | Software, computer, or network problems |
| Oil leaking from the tube housing | An emergency. Stop and call. |
Many of these show up as small changes first. Our guide to how often CT scanners should be serviced explains the intervals that catch them early.
How a CT repair visit works
- You contact us with the make, model, error logs, and symptoms.
- We diagnose on-site, reviewing fault history, the tube, cooling system, detector, gantry, and software.
- We explain your options. Before any major tube decision, we help you weigh whether the tube is the only major issue, whether parts are readily available, and how the scanner has performed over the last 12 to 24 months.
- We repair the system and run the needed calibrations, including air and water calibrations, detector normalization, and phantom scans.
- We verify performance and document the work before the scanner returns to clinical use.
Tube replacement: repair, replace, or wait?
CT tubes are wear items. By our field experience, CT tubes typically last about 12 to 36 months depending on volume and care, and heavy cardiac or interventional use shortens that. See when to replace a tube for warning signs and planning, and our repair cost guide for what drives price. Warm-up procedures matter too, since a cold tube is more prone to arcing.
CT repair in California: what to know about QA and dose
California regulates CT more tightly than most states. In general terms, SB 1237 (as amended) requires facilities that furnish CT services to be accredited, to record radiation dose on every CT study, and to have the displayed dose verified annually by a medical physicist, though accredited facilities may elect not to perform that verification. CDPH’s hospital inspection guide also lists physicist reports as required for CT units. The statute is available at leginfo.legislature.ca.gov.
What this means for repairs: after major component work, such as a tube replacement, detector work, or a software reload, coordinate QA with your medical physicist and your accrediting body. We document our calibrations to make that easy. This is general information, not legal advice, so confirm your obligations with your physicist, accreditor, and the Radiologic Health Branch.
Prevent repeat CT calls
- Preventive maintenance, typically twice a year, with more frequent service for high-volume, cardiac, or interventional systems. A full CT PM takes about 4 to 8 hours. See our CT service interval guide and complete PM guide.
- Cooling before summer. Triple-digit heat is common in the Sacramento Valley, and cooling faults are a common cause of unplanned CT downtime. Book spring PM and check your room’s HVAC.
- Don’t skip warm-ups and calibrations.
- Track outages. See our guide to imaging downtime costs and prevention.

Frequently asked questions
Do you repair all CT scanner brands?
We work on major manufacturers, including GE, Siemens, Philips, and Canon. Call with your make, model, and software version to confirm.
Do you replace CT tubes?
We diagnose tube problems and help you weigh repair, replacement, and timing. Call us with your system details to discuss tube options.
How long does a CT repair take?
It depends on the fault and parts availability. A simple repair can be a single visit, while a tube replacement or a part that must be ordered takes longer. A full CT PM, for comparison, takes about 4 to 8 hours.
How much does CT scanner repair cost?
It depends on what failed, and tube and detector problems are the large-ticket items. A written estimate after diagnosis is the only reliable number. See our cost guide.
Do you offer nights and weekend service?
Yes. We provide on-call overnight and weekend service.
How often should a CT scanner be serviced?
Most systems benefit from full PM about twice a year, with more frequent service for high-volume, cardiac, or interventional use. See our CT service interval guide.
Do I need a physicist after a CT repair?
After major component work, coordinate QA with your medical physicist and accrediting body. California also requires annual physicist verification of displayed CT dose unless an accredited facility elects not to perform it.
What are the signs my CT tube is failing?
Common signs include arc errors, failed warm-ups, cooling delays, bearing noise, aborted scans, and artifacts that calibration doesn’t clear. Oil leaking from the tube housing is an emergency.
