According to the documentation of imtool, if you do
hFigure = imtool(I,[]);
then hFigure is a handle to the figure created by the Image Viewer. If that is the case, then you might be able to manipulate the name of the figure as
set(hFigure,'NumberTitle','off','Name','show some description');

Thanks for your prompt answer.I get more knowledge about "title" function through your answer. And i have added the picure already.I want to add the title which is positioned in the example image to the imtool figure. If i use imshow function to show the image,the title can be add very easily through the code"title('title test')".But if i use imtool function,the title can not to add in the figure like the title in the example image. Thanks again.

Summer: I think these two code snippets should answer all your questions:
% First for a regular figure window.
s = uint8(randi(255, [512,512]));
hFig = figure
title('Title Test', 'FontSize', 15);
% Give a name to the title bar.
set(gcf, 'Name', 'Demo by ImageAnalyst', 'NumberTitle', 'Off')
% Now for the imtool window.
hToolFig = imtool(s);
set(hToolFig, 'Name', 'This is S in the imtool window');
% Note: close all won't close imtool windows.
% imtool close all; % Close all imtool figures if you have the Image Processing Toolbox.
