I have a total of 3281 .dcm images in a folder, they are each named differently. I am trying to extract certain fields from the headers of the DICOM images and create an array of each field that includes said field for all images to try to extract them to excel.

 %Specify the folder where the files live.
myFolder = 'D:\AUS\Masters\Mammography_Images';
% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(myFolder, '*.dcm'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
for k = 1 : 2
    baseFileName = theFiles(k).name;
    fullFileName = fullfile(theFiles(k).folder, baseFileName);
    fprintf(1, 'Now reading %s\n', fullFileName);
    if dicominfo(fullFileName).KVP~=0;
        KVP=dicominfo(fullFileName).KVP;
    else KVP=0;
    end
end

I am gettin the following error:

Reference to non-existent field 'KVP'.

Hi Reda,

You can use isfield to check whether a field exists in a structure.

Here is a similar question which has several different implementations for the same.

Hope this helps.

Hello Madhav,

Apologies for not replying sooner. I figured out how to only apply my code to actual images that include my parameters. Thank you very much for your help anyways.
