E.g. inhomogeneities in the detector image, instabilities in the dose rate or insufficient exactitudes in the axis system entail artifacts in the reconstruction of the volume data. Correction methods are applied in order to suppress the appearance of artifacts and to optimize the image quality.
Correction Methods and Data Improvement
Correction and Reduction of typical artifacts
- Circular ring artifacts
- Readout artifacts
- Double contours
- Foggy structures
- Dark stripes along long absorption edges
- Focal spot migration
- Noise
- image persistance
- Detector scattering
- Object scattering
- Focal spot expansio
