• To further optimize MPR image quality we recom-
mend that you reduce one or more of the following:
collimation, reconstruction increment, and slice
width for image reconstruction.
• With CAREDose 4D the mA values are adapted for
each osteo range, according to the patient diameter.
Therefore special obese protocols for the osteo eval-
uation are not longer necessary.
Body Kernels
• 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, lung, the kernels B50s, B60s, B70s, B80s are
available.
