Classification: CPC A | IPC A

Claim 0:
1. A method for compensating scattering of an X-ray image, the method comprising:
(a) receiving an original X-ray image as an input;
(b) initializing a primary image into the original X-ray image;
(c) estimating a scattered image from the primary image;
(d) updating the primary image by using the original X-ray image and the scattered image;
(e) judging whether a termination condition is satisfied;
(f) iterating steps (c) to (e) above by using the primary image updated through step (d) above into the primary image for step (c) above when the termination condition is not satisfied; and
(g) outputting the primary image updated through step (d) above as a scattering compensated image when the termination condition is satisfied,
wherein in step (c) above, the scattered image is estimated by using a scatter kernel defined for each thickness, and
wherein step (c) above includes
creating a water equivalent thickness (WET) map from a flat field image and the primary image, and
estimating the scattered image by using the WET map and the scatter kernel.
