what is a software phantom?

I think it has something to do with images although when I tried googling it this white small airplane model looking object flooded my screen but that is not what I am talking about. Can someone explain what it is or possibly point me to a source that could give me more information about it?

Thanks -Neo

I didn’t have any more luck that you did with a Web search. I believe it is a computed model of a specific shape (rather than an actual image of one) used to test computerized tomography algorithms. See for example the documentation for iradon in the Image Processing Toolbox.
