Siemens SOMATOM Sensation 16 - Kernel; Image Filter

General
Kernels
There are 5 different types of kernels: “H“ stands for
Head, “B“ stands for Body, “U“ stands for Ultra High
Resolution, “C“ stands for ChildHead, and “S“ stands
for Special Application, e. g., Osteo CT.
The image sharpness are defined by the numbers –
the higher the number, the sharper the image; the
lower the number, the smoother the image.
Note: Do not use different kernels for other body parts
than designed for.
Image Filter
There are 4 different filters available:
PFO: To reduce beam-hardening artifacts in head
images, particularly in the base of the skull, use the
Posterior Fossa Optimization (PFO) filter.
ASA: The Advanced Smoothing Algorithm (ASA) filter
reduces noise in soft tissue while edges with high con-
trast are preserved.
LCE: The Low-contrast enhancement (LCE) filter
enhances low-contrast detectability. It reduces the
image noise.
HCE: The High-contrast enhancement (HCE) filter
enhances high-contrast detectability. It increases the
image sharpness.
