Abstract
Methods and Apparatus for reducing image artifacts when reconstructing an image with a multislice computed tomographic (CT) imaging scanner are provided. Scout images are generated by obtaining a plurality of projection views of an object, modifying the projection data utilizing a deconvolution kernel, generating a horizontal gradient and a vertical gradient based on the modified projection data, applying helical weights to the horizontal gradient and vertical gradient, and applying a desired level of enhancement to the weighted horizontal and vertical gradients.
