Ass.-Prof. Dr. Sepideh Hatamikia has collaborated in a new paper with title ‘On Krylov methods for large-scale CBCT reconstruction’ which is published at Physics in Medicine and Biology Journal (https://iopscience.iop.org/article/10.1088/1361-6560/acd616). This research was a collaboration mainly with University of Cambridge, Department of Applied Mathematics and Theoretical Physics (DAMTP).
This research attempts to provide a general framework for the most relevant Krylov subspace methods applied to 3D CT problems. This is provided within an open source framework: the Tomographic Iterative GPU-based Reconstruction (TIGRE) toolbox, with the idea of promoting accessibility and reproducibility of the results for the algorithms presented. Numerical results in synthetic and real-world 3D CT applications (medical cone beam CT (CBCT) and μ-CT datasets) are provided to showcase and compare the different Krylov subspace methods presented, as well as their suitability for different kinds of problems.
