How to view dicom images on different planes (coronal, sagittal, transverse)

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: ct3d = NaN([siz_img N]); ct3d(:,:,1) = img;

% load all the remaining images and put them in the matrix for i=2:N strfile = sprintf('Z01',i); ct3d(:,:,i)= dicomread(fullfile(img_dir, strfile)); end

figure imshow(ct3d(:,:,i));

figure imshow(ct3d(:,:,3,1)); %transverse plane, first slice.

figure imshow(imrotate(squeeze(ct3d(:,55,1,:)),90),[]); %sagittal plane, 55th slice

I dont like the result. I cannot apply montage function and the image (first slice that comes out is of very poor quality).

Any suggestion?
