create the pixel size for Dicom_Picture in matlab

I have pictures in .dcm format. From Dicominfo I learned that the pixel spacing is [0.9,0.9] mm and the slice thickness is 1.98 mm.

My task: I should get the picture size in real (world) coordinates and then display the pictures in all three projections in matlab.

I had an idea that I would create a matrix in matlab, but it is difficult for me to create the pixel size spacing. I mean that the pixel in the matrix is like a square and is 0.9mm * 0.9mm. I don't know if my approach is correct and if there is an easy way to solve the problem. Thank you very much for every answer

several plotting functions allow you to specify x/y/z positions of each pixel/voxel, including imagesc, pcolor, here is an example using imagesc.

% vol stores your dicom volume
vol=rand(40,50,30);
dx=[0.9,0.9,1.98];
imagesc((0:size(vol,1)-1)*dx(1), (0:size(vol,2)-1)*dx(2), vol(:,:,1))
