Hi everyone,
I want to segmentation a 3D image, I have a series of DICOM CT scans and I want to convert it to volume image and to load it with volume viewer to do segmentation.
Can Someone knows such work?

Have you looked on the file exchange? There are dozens of readers and 3D viewers.

Refer the example code below,
close all; clc;
% Load the demo DICOM image
[X, map] = dicomread('US-PAL-8-10x-echo.dcm');
% Display the DICOM image
montage(X, map, 'Size', [2 5])
% Remove dimensions of length 1
X = squeeze(X);
% Launch volume viewer
volumeViewer(X)
% K-means clustering based volume segmentation
L = imsegkmeans3(X, 3);
% Visualize the segmented volume
volumeViewer(L)
Hope this helps!

@ eran bamani As rightly pointed out by Rik, please do not share the files. Refer the below code, it reads example DICOM data from a folder to form a volume.
close all; clc;
% Load the demo DICOM images from a folder
[V, spatial, dim] = dicomreadVolume(fullfile(matlabroot,'toolbox/images/imdata/dog'));
% Display the DICOM slices
montage(imadjustn(V), 'Size', [2, 11])
% Remove dimensions of length 1
V = squeeze(V);
% Launch volume viewer
volumeViewer(V)
% K-means clustering based volume segmentation
L = imsegkmeans3(V, 3);
% Visualize the segmented volume
volumeViewer(L)

'it didn't work' is not helping us to solve your issue. What release of Matlab are you using, what exact code are you running, and what is the exact and complete error message?
