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');

Can you show me a proper example? there is a insert button with listbox and one axes to show the DICOM images.

[Walter Roberson]

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.

I dont know why my axes(OutputDicom) showed only black image. Can you help me check what is the problem?
