Abstract
A discrete pixel image field of view is expanded by correction of filtered and processed image data. The raw image data is processed through at least one continuous domain filter. Roll off at limits of a linear range of the filter result in loss or degradation of image data in the transition region. The filtered image data is digitized and the resulting values are stored in discrete frequency value bins. Correction values are applied to the image data in the discrete bins of the transition region to correct the filter roll off. At least a portion of the corrected data is added to the field of view data employed in the image reconstruction. The technique permits as much as several percent of the field of view to be recuperated from the transition regions.
