Automatic Bone Correction
The head protocols provide significant improvements
regarding image quality for heads. An automatic bone
correction algorithm has been included in the standard
image reconstruction. Using a new iterative technique,
typical artifacts arising from the beam-hardening
effect, for example, Hounsfield bar, are minimized
without additional post-processing. This advanced
algorithm produces excellent images of the posterior
fossa, but also improves head image quality in general.
Bone correction is activated automatically for body
region “Head”. The reconstruction algorithm for “Head”
also employs special adaptive convolution kernels
which help to improve the sharpness-to-noise ratio.
More precisely, anatomic contours are clearly dis-
played while noise is suppressed at the same time
without causing a blurring of edges.
