Abstract

Several recent results in x-ray ghost imaging will be outlined. This is an unusual form of imaging in which all photons, that are used to form an image, are never registered by a position-sensitive detector.  Applications to one-, two- and three-dimensional objects will be reported, as well as some developments
regarding the notion of synthesizing ghost-imaging signals via a linear combination of noise maps.
