how to prossess multiple dicom images?

hello everyone, I have a project to do in matlab and I face some problems. here is a part of my code:

metadata=dicominfo('filename.dcm'); p=metadata.(dicomlookup('0010','0040')); %sex q=metadata.(dicomlookup('0010','1030')); %weight z=metadata.(dicomlookup('0028','1053')); %rescale slope a=metadata.(dicomlookup('0008','0032')); %aquisition time h=metadata.RadiopharmaceuticalInformationSequence.Item_1.RadionuclideHalfLife; %half life i=metadata.RadiopharmaceuticalInformationSequence.Item_1.RadionuclideTotalDose; %injection dose t=metadata.RadiopharmaceuticalInformationSequence.Item_1.RadiopharmaceuticalStartTime; %injection time

my problem is that I want to ask for the path and matlab automatically select the whole image sequence so I don't want to add the image name in my code. so, I would probably like a similar function as dicominfo.

thank you

Hi Dimitra,

To process a sequence of DICOM images without manually specifying each file name, you can automate the file selection using MATLAB’s built-in functions. It will allows to dynamically read all DICOM files in a folder and extract relevant metadata such as patient weight, acquisition time.

folderPath = uigetdir('', 'Select folder containing DICOM images');

% Get a list of all DICOM files in the selected folder
dicomFiles = dir(fullfile(folderPath, '*.dcm'));

"uigetdir" opens a folder selection dialog, so you don’t need to hardcode file names. After that it will gather all ".dcm" files from the selected folder.

for k = 1:length(dicomFiles)
    % Get the full file path
    filePath = fullfile(folderPath, dicomFiles(k).name);
    % Your implementation
end

To access individual files you can then loop through the images as above.

I am also attaching the documentation link on "uigetdir" for your reference:
