Attempt to reference field of non-structure array.

I am trying to creat a stack of 2d dicom images and represent them in a 3d rotation axis.

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 ii=2:N
    strfile = sprintf('Z01',ii);
    ct3d(:,:,ii)= dicomread(fullfile(img_dir, strfile));
end

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

dVolume = squeeze(ct3d.D);

it comes up with an error at the dVolume line

dicomread returns a numeric array. So what do you expect ct3d.D to do?

Actually, I want to load a stack dicom images and have them displayed on the three planes (Sagittal, transverse, frontal).

@Stelios Fanourakis: then you should actually ask how to do that in your question.
