| Zusammenfassung: | A method and system are provided for removing or reducing the scatter within the image. In the present technique, two images are acquired at different energies such that one image, typically the higher energy image, provides an estimate of the scatter in the image. In one embodiment, the image providing the estimate of scatter is subtracted from the other image to provide a scatter-reduced image. In another embodiment, a low-frequency image is generated from the image providing the estimate of scatter and the low-frequency image is subtracted from the other image to provide the scatter-reduced image. One or more weighting factors, such as multiplicative weighting factors may be applied to the involved images prior to subtraction. |
