Hello Shruti, <div><br></div><div>you are right, the fusion tool is buggy. If I remember well, it (almost) works when the fusion image as pixel value in [0:1000]. We must rethink this tools that was initially intended to display dose distribution on a CT image and not really to fuse two images in a very general way. Could you please indicate us for what kind of usage you want to use this tool ?</div>

combination.</font></span></div>
