Could you please provide the code for displaying multiple dicom files on MATLAB?

[Walter Roberson]

projectdir = 'Directory/of/dicom/files/';
dinfo = dir( fullfile(projectdir, '*.dcm') );
filenames = fullfile(projectdir, {dinfo.name});
nfiles = length(filenames);
images = cell(nfiles,1);
for K = 1 : nfiles
    images{K} = dicomread(filenames{K});
end
montage(images)

Use subplot() or see the montage() function.

for example i have 4 images in one file for this

montage( filename,'size',[2,2]);

in this please tell me what i have to write in place of filename and size in my code??????

[REHANA M.B]

reply me..

[Walter Roberson]

montage() is best for the case where the images are in separate files. For example,

montage({'img1.jpg','img2.jpg','img3.jpg','img4.jpg'}, 'Size', [2 2])

If the images are in memory then you would use subplot() or you would use image() _carefully_.

If you have a single file that has all four images stored in it, then what kind of file is it?

[REHANA M.B]

those are in one folder which is on the desktop.. for that we need to give folder name or path name????

[REHANA M.B]

how to read those??

If you are using montage(), you could cd() to the directory the images are in and then use the basic file names like I show above. Or instead of cd()'ing to there, you could use an absolute path for each of the file names.

You cannot, however, pass montage() a pathname and a series of file names that are intended to be relative to that path: only directory-relative files names or absolute file names.
