"Compressive x-ray phase tomography based on the transport of intensity equation.." Opt Lett, Volume 38, Issue 17, pp. 3418 - 3421.1539-4794https://arxiv.org/abs/1304.5180https://hdl.handle.net/2144/23577We develop and implement a compressive reconstruction method for tomographic recovery of refractive index distribution for weakly attenuating objects in a microfocus x-ray system. This is achieved through the development of a discretized operator modeling both the transport of intensity equation and the x-ray transform that is suitable for iterative reconstruction techniques.p. 3418 - 3421OpticsContrast tomographyComputed tomographyAlgorithmsOptical physicsQuantum physicsElectrical and electronic engineeringOpticsArticle0000-0002-1316-4456 (Tian, Lei)
