Compressive Sensing Radiation Detector

One of the main issue of trying to use compressed sensing in the radiation world other than light is the ability to focus/shepperd radiation to the right detector as is done by the DMD element in the one-pixel camera from Rice. A different way to use compressed sensing is to have a very well known material next to the detector as in the in-situ detector of Lawrence Carin, Dehong Liu, and Ya Xue at Duke University. According to this Technology Review article, the good folks at MIT are looking are refracted radiation with a mask similar to the one shown on the side. One cannot but think that a similar set-up can be used to do compressed imaging with X-rays using this type of coded-aperture imaging in the same as what is done for hyperspectral imaging in David Brady's group.
