Dear all,
I have the dicom image as attached (1.3.12.2.1107.5.6.1.1131.30330121041902101908100000087.dcm in folder image). That have 360 slices.
Then my lecturer convert it into text file as attached (in folder Projections) just till slice no. 104. He used ImageJ software.
He asked their students to convert it using Matlab as my assignment.
Anyone can help me?

You may use function dicomread to read the DICOM image.
Then you can use function writematrix to write each frame into a text file.

Dear @Simon Chan, can you write the command for me please?

Noticed your results using ImageJ has rotated 90 degrees and hence function rot90 is used in the code.
Try the following:
I = dicomread('xxx.dcm'); % Your dicom file
Nz = size(I,ndims(I)); % Number of frames
for k = 1:Nz
writematrix(rot90(I(:,:,1,k)),sprintf('%03d.txt',k)); % Write into txt file
end
