Create GIF of MRI Data Slices using Orthoslice Viewer

Open Live Script

Load MRI data and view it in the Orthoslice Viewer.

load(fullfile(toolboxdir('images'),'imdata','BrainMRILabeled','images','vol_001.mat'));
s = orthosliceViewer(vol);

Get the handle of the axes that contains the slice.

[hXYAxes, hYZAxes, hXZAxes] = getAxesHandles(s);

Turn off crosshair for better visibility.

set(s,'CrosshairEnable','off');

Specify the name of the GIF file.

filename = 'animatedYZSlice.gif';

Create an array of slice numbers in the required direction. Consider the YZ direction.

sliceNums = 1:240;

Loop through and create an image at the specified slice position.

for idx = sliceNums
    % Update X slice number to get YZ Slice.
    s.SliceNumbers(1) = idx;
  
    % Use getframe to capture image.
    I = getframe(hYZAxes);
    [indI,cm] = rgb2ind(I.cdata,256);
  
    % Write frame to the GIF File.
    if idx == 1
        imwrite(indI,cm,filename,'gif','Loopcount',inf,'DelayTime',0.05);
    else
        imwrite(indI,cm,filename,'gif','WriteMode','append','DelayTime',0.05);
    end
