Body Kernels
The endings “s” or “f” depend on the rotation time.
• As standard kernels for body tissue studies B30s or
B40s are recommended; softer images are obtained
with B20s or B10s (extremely soft). The kernels B31s
or B41s have about the same visual sharpness as
B30s, respectively, B40s, the image appearance,
however, is more agreeable due to a ”fine-grained”
noise structure; quite often, the low contrast detect-
ability is improved by using B31s, B41s instead of
B30s, B40s.
• For higher sharpness, as is required e.g. in patient
protocols for cervical spine, shoulder, extremities,
thorax, the kernels B50s, B60s, B70s, B80s are avail-
able.
• The special kernels are mostly used for ”physical”
measurements with phantoms, e.g. for adjustment
procedures (S80s), for constancy and acceptance
tests (S80s, S90s), or for specification purposes
(S90s).
For special patient protocols, S80s and S90s are cho-
sen, e.g. for osteo (S80s).
• For very high sharpness we recommended the U70u,
U80u, U90u for bone studies. UHR mode has a max-
imum FoV of 300 mm.
It is mandatory to position the area of interest in the
center of the scan field. Use ExtrCombi mode when a
scan FoV > 25 cm is necessary.
