Kernels

There are 4 different types of kernels: "H" stands for
Head, "B" stands for Body, "C" stands for ChildHead and
"S" stands for Special Application, e.g. syngo Osteo CT.
The image sharpness is defined by the numbers – the
higher the number, the sharper the image; the lower
the number, the smoother the image.
