How to remove glitch artifact from image ?

Hi

I removed the criss-cross artifact in this image (below) using the code below. The code i used remves the noise in frequency domain. However, am wondering, can i correct this artifact in the special domain

LS=imread('MRIjpg'); 
LS=rgb2gray(LS);
figure(1);imshow(LS);title('Original')
f=fft2(LS);
fm=fftshift((f));
sd1=log(abs(fm));
figure(3), imagesc(sd1);title('FFT space')
Fm=fft2(LS); 
Fm1=fftshift(Fm); 
Fm1(440:460,320:340)=0; 
Fm1(380:400,380:400)=0;
figure(2), imagesc(log(abs(Fm1)));title('FFT Filter')
ND=abs(ifft2(Fm1));% adjusting the inverse of the fft image 
figure(3), imagesc(ND); title('output') 
colormap('gray')%
