dinfo = dir('*.dcm');
dcm_files = {dinfo.name};
set( handles.listbox1, 'String', dcm_files);
...
function listbox1_Callback(src, event, handles)
box_choices = get(src, 'String');
box_chosen = get(src, 'Value');
file_chosen = box_choices{box_chosen};
[ImageData, ImageMap] = imread(file_chosen);
imshow( ImageData, ImageMap, 'Parent', handles.axes_to_display_in);
axis(handles.axes_to_display_in, 'image');

That is a proper example. Just change "listbox1" to the Tag you used for your listbox, and change "axes_to_display_in" to the tag you used for the axes to display the image in.

set(hObject,'BackgroundColor','white');
end
return
I dont know why my axes(OutputDicom) showed only black image. Can you help me check what is the problem?
