Scan and Reconstruction
Improved Head Imaging
The software version syngo CT 2006G provides signifi-
cant 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, e.g. Hounsfield bar, are
minimized without any additional post-processing.
This advanced algorithm allows for excellent images of
the posterior fossa, but also im-proves head image
quality in general. Bone correction is activated auto-
matically for body region “Head”. The reconstruction
algorithm for “Head” also employs special adaptive
convolution kernels which allow for improving the
sharpness to noise ratio. More precisely, anatomic con-
tours are clearly displayed while noise is suppressed at
the same time without causing a blurring of edges.
