# Fast reconstruction of low dose proton CT by sinogram interpolation

@article{Hansen2016FastRO, title={Fast reconstruction of low dose proton CT by sinogram interpolation}, author={David Hansen and Thomas Sangild S{\o}rensen and Simon Rit}, journal={Physics in Medicine \& Biology}, year={2016}, volume={61}, pages={5868 - 5882} }

Proton computed tomography (CT) has been demonstrated as a promising image modality in particle therapy planning. It can reduce errors in particle range calculations and consequently improve dose calculations. Obtaining a high imaging resolution has traditionally required computationally expensive iterative reconstruction techniques to account for the multiple scattering of the protons. Recently, techniques for direct reconstruction have been developed, but these require a higher imaging dose…
