Scan and Reconstruction
"HCE": The High-contrast enhancement (HCE) filter
enhances high-contrast detectability. It increases the
image sharpness, similar to reconstruction with a
sharper kernel.
• Increases sharpness
• Faster than raw-data reconstruction
• Enhances high-contrast detectability
• Automatic post-processing

the HCE filter
"ASA": The Advanced Smoothing Algorithm (ASA)
filter reduces noise in soft tissues while edges with
high contrast are preserved.
• Reduces noise without blurring of edges
• Enhances low-contrast detectability
• Individually adaptable
• Automatic post-processing
