Image Filters - Siemens SOMATOM Manual

Scan and Reconstruction

Image Filters

If you use kernels, the images are reconstructed again
with the selected kernel value. If you use image filters,
the images are not reconstructed again and the result
is much quicker.
Three different filters are available:
LCE: The Low-contrast enhancement filter enhances
low-contrast detectability. It reduces the image noise.
• Similar to reconstruction with a smoother kernel
• Reduces noise
• Enhances low-contrast detectability
• Adjustable in four steps
• Automatic post-processing
