  • Single-shot method for edge illumination X-ray phase-contrast tomography
    Patent number: 10598612
    Abstract: A method and systems of reconstructing a complex-valued X-ray refractive index distribution of an object having undergone X-ray phase-contrast tomography. The method includes acquiring at least one X-ray image of an object using an edge illumination X-ray phase-contrast tomography (EIXPCT) model, discretizing the model, jointly reconstructing the complex-valued refractive index distribution of the object using penalized least squares estimation of real and imaginary parts of the distribution, and solving the penalized least squares estimation using a batch gradient algorithm.
