Image noise reduction on the EMI 7070 CT scanner by the reduction of the noise resident in the CT wedge profiles.
On the EMI 7070 CT scanner the data contained in the wedge files has been averaged resulting in a 6% reduction in the noise content of images. This noise reduction can either be used to improve image quality or can be offset by reducing the x-ray tube current by 12%. The averaging method will be outlined and its rationale discussed.
