Abstract: Present multi-spectral CT approaches are able to cancel the noise from the combined (mono-energy) image. However, medical professionals also find it useful to consult the basis images which are combined (summed) form the mono image, because they can provide useful extra diagnostic information. However, denoising of the basis images can lead to a “jagged” appearance of edges in the denoised basis images, inconveniently requiring further image processing steps to take place before the basis images can be clearly read. Accordingly, there is provided an apparatus (30) for simultaneous edge noise reduction. The apparatus comprises a processor (32). The processor is configured to receive first (s0) and second (p0) input image data, and to receive first (s) and second (p) denoised input image data. The first and second input image data contains noise which is anti-correlated between the first and the second input image data.
