Hi all
I want to display multiple images using GUI. I have 135 image. i want load 135 images in axes, then when i slide, it will show the image from 1 to 135. This is my code that i know to read 135 image:
P = zeros(256, 256, 135);
for K = 1 : 135
petname = sprintf('PET_I1001_PT%03d.dcm', K);
P(:,:,K) = dicomread(petname);
end
how to me write the command for 'load image button' and 'slider' in m file ??
hope anyone can help me

Set up your scroll bar to have 135 as the max and 1 as the min. Then in the scrollbar callback function:
scrollBarValue = round(handles.scrollbar1.Value);
petName = sprintf('PET_I1001_PT%03d.dcm', scrollBarValue);
fullFileName = fullfile(folder, petName);
thisImage = dicomread(fullFileName);
imshow(thisImage);
No loop is needed.

This line is the line that loads the image from disk into a variable:
thisImage = dicomread(fullFileName);
This is the line that loads the image from a variable onto a rectangle on your screen:
imshow(thisImage);
