Why it comes up with only the first slice all the time?

I have 5 MRI images and need to load and stack them. I use the code below. It comes up with the first slice/image under 5 times. It does not load the 4 remaining images. Only the first image by 5 times. What to do?

clc; clear all; close all;

N=5; img_dir ='D:\Stelios PhD files'

strfile = 'Z01'; img = dicomread(fullfile(img_dir, strfile)); siz_img = size(img);

% create result matrix: D = NaN([siz_img N]); D(:,:,1) = img;

% load all the remaining images and put them in the matrix for i=1:N strfile = sprintf('Z01',i); D(:,:,i)= dicomread(fullfile(img_dir, strfile)); end

D=squeeze(D);

Ds=smooth3(D);

Probably you intended to write,

 sprintf('Z0%d',i);

instead of

 sprintf('Z01',i); %the outout here is always Z01
