Previous work has shown that total variation superiorization (TVS) improves reconstructed image quality in proton computed tomography (pCT). The structure of the TVS algorithm has evolved since then and this paper investigated if this new algorithmic structure provides additional benefits to pCT image quality. Structural and parametric changes introduced to the original TVS algorithm included: (1) inclusion or exclusion of TV reduction requirement, (2) a variable number, <inline-formula> <tex… 
Proton Computed Tomography: A Case Study for Optimal Data Acquisition
The study outcomes highlight the optimal acquisition for pCT reconstruction for superior image quality but there must always be a trade-off between noise and spatial resolution for optimal data acquisition.
Comparison of regularized and superiorized methods for tomographic image reconstruction
We compare two approaches to image reconstruction in computed tomography (CT) which incorporate penalty functions to improve image quality in the presence of noisy data. The first approach adapts a

Employing the CSP and MLP for iterative ion CT reconstructions enabled improved image quality over the SLP even in realistic and heterogeneous patient anatomy, however, only limited benefit in dose calculation accuracy was obtained even though an ideal detector system was simulated.
An Iterative Least Squares Method for Proton CT Image Reconstruction
It is found that it is possible, for any object being imaged, to provide assurance that the image is quantifiably close to an optimal solution, and the optimization of step sizes reduces the total number of iterations required for convergence.

Error analysis for filtered back projection reconstructions in Besov spaces
It is proved that the $\mathrm{L}^p$-norm of the inherent FBP approximation error can be bounded above by under suitable assumptions on the utilized low-pass filter's window function $W$.
An optimization algorithm for dose reduction with fluence-modulated proton CT.
A uniform fluence field was shown not to be dose optimal and dose reductions achievable with the proposed method for fluence-modulated proton CT were considerable, opening an interesting perspective for image guidance and adaptive therapy.

Total variation superiorization schemes in proton computed tomography image reconstruction.
The authors investigate the use of total variation superiorization (TVS) schemes that can be applied as an algorithmic add-on to perturbation-resilient iterative projection algorithms for pCT image reconstruction, finding that low-contrast imaging made possible with TVS holds a promise for its incorporation into future pCT studies.
