One figure instead of 100 and scroll.

64 views (last 30 days)
I am trying to scroll through a whole stack of CT images. So in order for this to work, I have to open lets say 100 separate figure windows and then smoothly scroll through them. However - how can I just open ONE figure window and have ALL my images be scrolling through in it?

I am not sure what you mean by a "stack" of CT images. If you mean a 3D reconstruction, then maybe FEX:SliceBrowser does what you want. If you want a bunch of subplots with a scroll bar on the figure maybe technical note 1-16B5M helps you.

You could easily write a simple tool that would take a stack of images, creating a figure with a scroll bar on it. Callbacks from the scroll bar would let you move to any image in the stack, stepping along or jumping as you might desire. But you would need to write the code for that task. Simple, but not currently in existence that I know.

Actually, this is what I was looking for :
function windowScrollWheelFcn(hObject, eventData)
if (eventData.VerticalScrollCount > 0 && currentIndex>start)
currentIndex = currentIndex - 1;
drawImage(currentIndex)
elseif (eventData.VerticalScrollCount < 0 && currentIndex<fin)
currentIndex = currentIndex + 1;
drawImage(currentIndex)
end
function drawImage(index) clf(handleFigure) fprintf('Image %d\n', index) subplot(2,2,[1 3]);
%draw the different pictures
imshow(I{index},'DisplayRange',[], 'XData', [info{index}.ImagePositionPatient(1) info{index}.ImagePositionPatient(1)+info{index}.PixelSpacing(1)*double(info{index}.Columns)],...
'YData',[info{index}.ImagePositionPatient(2) info{index}.ImagePositionPatient(2)+info{index}.PixelSpacing(1)*double(info{index}.Rows)]);
iptsetpref('ImshowAxesVisible','on');
hold on;
plot(x{index},y{index},'.');
axis equal
subplot(2,2,[2 4]);
plot(xcomp{index},zcomp{index},'.');
hold on;
xlim([min(xcomp{index})-10 max(xcomp{index})+10])
axis equal
plot(domaine{index},hauteur{index},'r-')
end
