| Abstract: | A ring artefact suppression algorithm in x-ray tomography is proposed and allows one to process input data in real time. The algorithm is based on methods of the theory of inverse and ill-posed problems. Its numerical implementation uses minimisation of the smoothing Tikhonov’s functional with the conjugate gradient method. |
