Is it Debris?

Some artifacts are due to dirt, dust or debris that have found their way inside the system.

Others can be debris from inside the C-Arm’s image intensifier. Sometimes the phosphor lining inside the system can break down and flake off. That can mean that a serious part needs to be replaced. If your C-Arm has a bad or broken connection, or failure among the parts in the image processing chain, you can also get digital artifacts.

Let’s Start Troubleshooting

First, you need to determine the nature of your image artifact. Take a close look at the artifact’s appearance. Those caused by debris are usually specks or spots without rounded, blurred edges. They can also appear as streaks. Digital artifacts, on the other hand, tend to be squarer or pixelated in appearance, with edges that are clean.

If you think the cause of the artifact is physical, you need to locate the debris in your system.

You can find lint or dust in a lot of different places within your C-Arm, but if it’s in the image, it’s definitely in one of four different places: the camera, collimator, the II or the tube port.

The first step is to perform a simple magnification test. Take an image in the normal mode.

Note the size and position of the image artifact. Next, take the same image in mode 1 or mode 2 and see if it changes size or position. If it stays the same size, that means it’s either in the top of the II lens or in the camera. If the artifact changes size or position, the debris

is either in the lower part of the II or the tube port.

Next Steps

If your artifact didn’t change during the magnification test, the next thing to do is clean the camera lens. Use an air puffer like the ones used to clean a regular photo camera lens.

These cost about $10. You’ll find them where handheld cameras are sold. If the lens has a

smudge on it, use an eyeglass cloth to wipe it away. If cleaning the lens doesn’t remove the artifact, chances are you have to replace the camera.

If the artifact magnifies when tested, you need to clean the grid on the II, the collimator and the tube port. Only use the air puffer on the silver part when cleaning the grid. If you can’t clean it away, in all likelihood you’ll have to replace the camera, as well.

If it’s a digital artifact, the issue is usually with one of the image processing boards. Has it

been caused by a poor connection at a board or cable? Reseat the cables and boards to ensure strong connections. If that doesn’t work, it’s time to contact a technician.
