Claim 7:
8. An apparatus for compensating scattering of an X-ray image, the apparatus comprising:
an image input unit receiving an original X-ray image as an input; and
an image processing unit outputting a scattering compensated image for the original X-ray image,
wherein the image processing unit initializes a primary image into the original X-ray image, performs a first process of estimating a scattered image from the primary image, a second process of updating the primary image by using the original X-ray image and the scattered image, and a third process of judging whether a termination condition is satisfied, and iteratively performs the first to third processes by using the primary image updated through the second process into the primary image for the first process when the termination condition is not satisfied and outputs the primary image updated through the second process as the scattering compensated image when the termination condition is satisfied,
wherein the image processing unit estimates the scattered image by using a scatter kernel defined for each thickness in the first process, and
wherein the image processing unit creates a water equivalent thickness (WET) map from a flat field image and the primary image and estimates the scattered image by using the WET map and the scatter kernel, in the first process.
