Fraunhofer Institute for Integrated Circuits IISInadequacies in your X-ray system can compromise optimum image quality. For example, inhomogeneities in the detector image, instabilities in the dose rate, or insufficient accuracy in the axis system can lead to artifacts in the reconstruction of the volume data. Correction methods are used to counteract this, which suppress the formation of artifacts and optimize image quality.
Correction and data enhancement
Correction and reduction of typical artifacts
- Circular ring artifacts
- Readout artifacts
- Double contours
- Cloudy structures
- Dark stripes along the absorption edge
- Focal spot migration
- Noise
- Image retention artifacts
- Detector scattering
- Object scattering
- Focal spot expansion
