Temporal and spectral reconstruction algorithms for x-ray CT

Published

Journal Article

X-ray CT imaging of dynamic physiological processes entails the reconstruction of volumetric images of objects with x-ray attenuation properties that vary over time and energy. We show how the same algebraic model can be used to represent both temporal and spectral information. This model enables the formulation of algorithms capable of recovering information in either dimension. These dimensions can also be combined to develop algorithms that recover both dimensions simultaneously. We present such an algorithm, describe its implementation, and test it in simulations. © 2011 SPIE.
