Ghost imaging (GI) is an unconventional imaging technique that creates an image of an object by using a single-pixel detector and a reference beam. Theoretical studies show that it is possible, in principle, to reduce dose with GI given prior knowledge of the sample. In particular, GI has the potential to produce an image of an object with a small number of photons, compared to traditional imaging techniques. When using ionizing radiation, this implies that ghost imaging might be able to produce an image with much less radiation exposure to the patient or object, when compared with conventional imaging. A key parameter that is crucial to the success of ghost imaging is the mask (or device), which is placed upstream of the object to produce the illumination pattern as recorded in the reference beam. The choice of illumination patterns can affect the contrast and the resolution of the reconstructed image. I introduce a range of illumination patterns and the GI mask that we have designed and fabricated on a glass substrate. I explain the fabrication process and present experimental X-ray GI results obtained using a laboratory X-ray source.
