Viewing same slice of 2 different image stacks with sliceViewer

I have a CT reconstruction and the relative segmentation, both image stacks made by 140 slices. I'm using sliceViewer to display them in two different figures:

fig1 = figure("Name","CT image", "NumberTitle", "off");

s1 = sliceViewer(imm);

fig2 = figure("Name","Segmentated image", "NumberTitle", "off");

s2 = sliceViewer(seg);

I would like to see the same slice of both images by sliding only one of them. I'm trying to use the line

s2.SliceNumber = s1.SliceNumber

but it works only once, while i need to repeat this line every time I use the slider of s1.

Any idea? Thank you for the help!

Hi,

To achieve this, you can add a listener to the "SliceNumber" property of s1 that updates the "SliceNumber" property of s2 whenever it changes.

% Add listener to s1
addlistener(s1, 'SliceNumber', 'PostSet', @(src,evt) updateSliceNumber(s1, s2));

function updateSliceNumber(s1, s2)
    % Update the SliceNumber property of s2 to match s1
    s2.SliceNumber = s1.SliceNumber;
end
