Hints

•An automatic bone correction allows for improved head image quality, without any additional post-pro- cessing.

•In order to optimize image quality versus radiation dose, scans are provided within a maximum scan field of 300 mm with respect to the iso-center. No recon job with a field of view exceeding those limits will be possible. Therefore, patient positioning has to be performed accurately to ensure a centered loca- tion of the skull.
