Hologic DEXA HV Tank Troubleshooting

Is your Hologic DEXA machine locking up, tripping breakers, or showing streaks and lines in your scanning field?

If any of these problems are happening regularly at your facility, your system might have a failing high voltage (HV) tank. The high-voltage tank is a major component of your DEXA system, and its failure can cause downtime in your patient schedule.

Fortunately, these tanks are readily available on the secondary market and, with a few troubleshooting steps, you can determine if yours is suspect. We'll share below what you should look for to determine if your Hologic DEXA HV tank is on its way to failure.

Check Your X-Ray Cup for Oil

The symptoms and failures mentioned above are frequently due to oil leakage from the tank. Oil leakage can accumulate in the X-ray cup, restricting X-ray emission. It can also lead to electrical arcing, which can shut your system down or damage other components. Check your X-ray cup for leaked oil by removing the cover pictured below. If you have oil in the cup, contact your service provider.
