A fast weighted stochastic gradient descent algorithm for image reconstruction in 3D computed tomography

RababKreidieh Ward

Abstract—We describe and evaluate an algorithm for image reconstruction in 3D x-ray computed tomography. The proposed algorithm is similar to the class of projected gradient methods. The gradient descent for reducing the measurement misfit term is carried out using a stochastic gradient iteration and the gradient directions are weighted using weights suggested by parallel coordinate descent.
