to display multiple images on a single frame

I tried to display a X-Ray image .. and it successfully working. the code is below..

Y = dicomread('C:\Users\Rehana\Desktop\dicom\test.DCM');

imshow(Y);

imcontrast;

but getting error in the below code, here i am trynig to display multiple images on a single frame .. please help me..

load dicom

[X2,map2] = imread('C:\Program Files\MATLAB\images\'test'*.DCM');

subplot(1,2,1), subimage(X,map)

subplot(1,2,2), subimage(X2,map2)

in this case 'images' is one folder where i stored test1.DCM, test2.DCM,test3.DCM,test4.DCM ( samples of x-ray images )files.

What is the error message?

Hi,

It seem you tried to display multiple dicom files in a folder but you use wrong syntax.

And please don't use imread to read dicom file. Use dicomread instead.

Assume that I have 4 dicom files in folder named 'New Folder'.

files = dir(fullfile(pwd,'New Folder\*.dcm'));
for i = 1 : numel(files)
    [X map] = dicomread(fullfile(pwd,'New Folder',files(i).name));
    if ~isempty(map)
        subplot(2,2,i); 
        subimage(X,map);
    else
        subplot(2,2,i); 
        imshow(X,[]);
    end
end

Thanks Mr.Chandra.. I have seen your Youtube videos on Matlab, Helped a lot thank you.

I tried your code my code is like this

files = fullfile('C:', 'Program Files','MATLAB','images\*.DCM');

for i = 1 : numel(files)

[X, map] = dicomread(fullfile('C:','images',files(i).DCM));

if ~isempty(map)

subplot(2,2,i);

subimage(X,map);

else

subplot(2,2,i);

imshow(X, map);

end

end

In this code The function dicomread() is giving the error.. help this thanks for advance

[REHANA M.B]

The error is

??? Improper index matrix reference.

Error in ==> Untitled3 at 3

[X, map] = dicomread(fullfile('C:','images',files(i).DCM));

[Chandra Kurniawan]

Please try my code below :

files = dir(fullfile('C:','Program Files','MATLAB','images\*.dcm'));

for i = 1 : numel(files)

[X, map] = dicomread(fullfile('C:','Program Files','MATLAB','images',files(i).name));

if ~isempty(map)

subplot(2,2,i);

subimage(X,map);

else

subplot(2,2,i);

imshow(X, map);

end

end

If your file extention was DCM then you can change them yourself.

[REHANA M.B]

Actually it didnt have extension after downloading.. so i renamed it.

[Chandra Kurniawan]

I recommend you to use a DCM file in good condition.

Renaming the file does not guarantee and too risky.

[REHANA M.B]

its working .. Thanks Mr.Chandra..

[Chandra Kurniawan]

glad to help you :)

[REHANA M.B]

See i have some plan to display it in other way..

like ..on a single frame, assume we have already displayed ( left side of the frame ) some sets 2 or 3 sets of image files which contains 4 images each. and right side of the image selected image sets should be display by clicking on left side image sets..

can it possible?????

[Chandra Kurniawan]

So, by using mouse click?

I think it's hard to do.

I do not know if anyone else can probably do this with some trick.

[REHANA M.B]

ya mouse click..

with building GUI we can do know??

[REHANA M.B]

Mr.Chandra do you know any text books or any references, sites for learning displaying images in different ways on matlab?? (image processing on matlab).

let me know please..

i hit google for that but unable to get a good one.

[REHANA M.B]

Hey please tell me how do i display it on GUI with pushbutton??
