This chapter investigates more carefully this step of image formation from digitized focused k-space data and discusses techniques for obtaining imagery with improved resolution and reduced sidelobes compared with imagery obtained simply using the weighted FT. The authors also introduce two other definitions: Signal processing, which is the processing of the k-space signal to form an image; Image processing, which is additional processing performed on the image to improve the contrast, resolution, and so on.
