How to split DICOM to individual slices?

Here I have attached a stacked dicom file comprising 28 slices. How can I save individual dicom files for each slice?

To save individual DICOM files for each slice from a stacked DICOM file in MATLAB, you can use the "dicomread" function to read the stacked DICOM file and then iterate through each slice to save it as a separate DICOM file using the "dicomwrite" function.

stackedFileName = 'path_to_stacked_dicom.dcm';
volumeData = dicomread(stackedFileName);

info = dicominfo(stackedFileName);

numSlices = size(volumeData, 3);

for sliceIdx = 1:numSlices

    sliceData = volumeData(:, :, sliceIdx);
    
    info.InstanceNumber = sliceIdx;
    info.SliceLocation = sliceIdx; % Update slice location if necessary
    
    % Construct a filename for the slice
    sliceFileName = sprintf('slice_%02d.dcm', sliceIdx);
    
    % Write the slice to a new DICOM file
    dicomwrite(sliceData, sliceFileName, info);
end
