Head Kernels - Siemens SOMATOM Emotion 6 Application Manual

Children

Head kernels:

• For head scans of small children, the kernels C20s,
C30s (e. g. for soft tissue studies) and C60s (e. g. for
sinuses) should be chosen instead of the "adult" head
kernels H20s, H30s and H60s.
• For soft tissue head studies, the standard kernel is
H40s; softer images are obtained with H30s or H20s,
H10s, sharper images with H50s. The kernels H21s,
H31s, H41s yield the same visual sharpness as H20s,
H30s, H40s, but a more agreeable image appearance
and sometimes even better low contrast detectability,
the reason is, as with B31s and B41s, the fine-grained
noise structure.
• For the standard head protocols, we propose H21s,
H31s, H41s.
• High resolution head studies should be performed
with H60s, H70s (e. g. for dental and sinuses) and
H80s, H90s (e. g. inner ear).
