This DCM image is opened in ITK SNAP . I want to process this image in matlab using only its axial view which is in top left corner.

dear zubda do use this code
clear all
close all
clc
a=imread('ct.png');
figure(1)
imshow(a)
b=~(a(:,:,1)==240 & a(:,:,2)==240 & a(:,:,3)==240);
figure(2)
imshow(b);
[m,n]=size(b);
[lab,num]=bwlabel(b);
for i=1:num
[r,c]=find(lab==i);
loco(i,:)=[i mean(r) mean(c)];
end
loco(:,4)=sqrt( (loco(:,2)-m*0.2885).^2 + (loco(:,3)-n*0.7794).^2);
loco=sortrows(loco,4);
[r,c]=find(lab==loco(1,1));
c=a(min(r):max(r),min(c):max(c),:);
figure(3)
imshow(c)

try to solve as many tasks as you can for basics of matlab, do evolve your own little tasks whatever you think and do try to solve that with matlab. rest matlab help is the perfect for knowing commands and fuctions.
