I have a database of lung Ct scans in Dicom format. In ITK snap 3 views of image are opened. I just want to open axial view of CT in matlab. How can I do that?

在 MATLAB Online 中打开

dear zubda do use this code

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)

Thank you Sir for your help. Code is working. :) Can you please guide me to some good matlab tutorial source where I can learn and understand code and get help for errors in my code?

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.
