  • Method and apparatus for compensating scattering of X-ray image
    Patent number: 11911202
    Abstract: Provided is a method for compensating scattering of an X-ray image, which includes: (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.
