Dear all,
Anyone know how convert dicom file to mat file?
the dicom file as attached.
I've tried this code. but got error.
clc
clear all
[spect map] = dicomread('Khadijahkalai.dcm');
size(spect);
spect = squeeze(spect);
for k = 1:142
matwrite(P(:,:,k),sprintf('I-13125610N125666666%03d.dcm',k));
end

assign the slice to a variable. Call save() passing in the file name and the name of the variable (as a character vector.)
spectslice = spect(:, :, k);
filename = sprintf('I-13125610N125666666%03d.mat',k);
save(filename, 'spectslice')
This assumes that you have good reasons to save each slice as a separate mat file, which we are having trouble thinking of a good reason to do. It would be more common to save the entire array as one mat, or to save slices as images.

If you really want to store every slice as a separate mat file (which I don't understand why you would want that):
dicom_filename='I-13125610N1256x25672-95.dcm';
[spect,map] = dicomread(dicom_filename);
spect = squeeze(spect);
for k = 1:24
matfilename=sprintf('%s_%03d.mat',dicom_filename,k);
spect_slice=spect(:,:,k);
save(matfilename,'spect_slice')
end
