Hello, I have a problem with coloring my dicom loop. I have a GUI for loading and displaying DICOM loop from ultrasound. Im using function image for displaying loop because this function is the best option with timing for me }functions as imshow and so on are too slow). The loop should be black and white, but after displaying its blue and yellow. Could anyone help me how can I change the coloring of the loop? Thanks

for i = 1 : nFrames cla reset image(loading_dicom(:,:,i)) pause(0.0001);

end

I used imshow first, the color was good but it was too slow for me.

在 MATLAB Online 中打开

colormap(gray(256))

Note: because timing is important to you, you should be coding something like,

for idx = 1: ....
   ...
   if idx == 1
     ih = image(YourData);
     colormap(gray(256));
   else
    set(ih, 'CData', YourData);
   end
   title( sprintf('Slice #%d', idx) );
   drawnow();
 end
