apply equations to all of the dicom images in a file

Hi there

I made a code to calculate a parameter in heart out from a set of images (scan). Each scan contians 16 frames. I have 100 of these scans. I have to creat a manual region of interest (roi) for each scan . I would like the code to read each dicome scan in the file, allow me to draw roi and then apply my equation to each scan seperatly. I also want to view the final results. Briefly, i would like MATLAB to apply function to multiple scans.

I am sorry if my question is selly, i am new to MATLAB. Below is my code

imvol = dicomread(squeeze('LAO-Ga003_DS.dcm'));
% create binary masks for each image
imshow(sum(imvol,3),[]) %display image
maskim=roipoly; % drow the mask to be multiplied by the image (or synchrony results). 
    
for ii=1:128
    for j=1:128
        phaseim(ii,j,:)=angle(fft(squeeze(imvol(ii,j,:))))';
        ampimage(ii,j,:)=real(fft(squeeze(imvol(ii,j,:))))';
        fftimage(ii,j,:)=fft(squeeze(imvol(ii,j,:)))';
    end
end 
   sync=(sum(sum(squeeze(ampimage(:,:,2)).*maskim)))/sum(sum(squeeze(abs(fftimage(:,:,2).*maskim))));

You can have a for loop that reads in each image and the runs the code you want.
