WebApr 29, 2024 · Metal artifacts still cause great concern in dental CT imaging since the artifacts greatly compromise the image readability even after MAR. In our previous study, we showed that dual-energy imaging can greatly reduce the metal artifacts. However, the dual-energy imaging approach is costly in terms of scan time and X-ray exposure. Web1. X-rays should be emitted from the smallest source of radiation as possible: Improves image resolution Reduces geometric unsharpness: 2. X-ray source-to-object distance should be as long as possible: Improves image sharpness Reduces magnification: 3. Object-to-receptor distance should be as short as possible: Improves image sharpness Reduces ...
