Metal artifacts are noise when imaging samples that are difficult for X-rays to penetrate, such as metals. When composite materials are CT scanned, metallic artifacts are streak-like artifacts that occur around metallic parts.
Countermeasures include reduction during CT scan imaging and reduction in image processing (reconstruction).
The following methods can be used to reduce the amount of light during shooting. Increase the X-ray tube voltage. The irradiated X-rays are filtered with a copper plate or similar material to suppress the effects of beam hardening for projection.
