Hello erveryone,

I need to display a directory with 300 dicom images, and one of them it is the one which I want to crop to work later in other function. I have created this function:

for z=1:size(directory)
     archive = directory(z).name;
     R3 = (dicomread(archive));
     R3=imadjust(R3);
     imshow(R3);
     pause(3)
%                cro=imcrop(R3);
end

I have included a 3 seconds pause to watch each image, but I don't know how to include the imcrop condition when I see the correct image to save this crop and get out of the function.

Could you help me?

Thanks!

Put this in your loop:

promptMessage = sprintf('Do you want to Crop this image,\nor Skip this image?');
titleBarCaption = 'Continue?';
button = questdlg(promptMessage, titleBarCaption, 'Crop', 'Skip', 'Skip');
if strcmpi(button, 'Crop')
  croppedImage = imcrop(R3);
end
