Journal ArticleDOI
A maximum likelihood proton path formalism for application in proton computed tomography
TL;DR: A compact, matrix-based most likely path (MLP) formalism is presented employing Bayesian statistics and a Gaussian approximation of MCS to predict the Monte Carlo tracks of 200 MeV protons in GEANT4 simulations.
Journal ArticleDOI
Total variation superiorization schemes in proton computed tomography image reconstruction
TL;DR: 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.
Journal ArticleDOI

TL;DR: This review paper summarises and discusses a selection of representative papers with the aim of providing an overview of a) geometrical descriptions of biological targets down to the DNA size, and b) the full spectrum of current micro- and nano-scale applications of Geant4-DNA.
Journal ArticleDOI
Monte Carlo investigation of the increased radiation deposition due to gold nanoparticles using kilovoltage and megavoltage photons in a 3D randomized cell model
TL;DR: Investigation of increased radiation dose deposition due to gold nanoparticles (GNPs) using a 3D computational cell model during x-ray radiotherapy shows that the primary dose enhancement is due to the production of additional photoelectrons.
Journal ArticleDOI
A more accurate reconstruction system matrix for quantitative proton computed tomography
TL;DR: The purpose of the present work was to introduce a computationally efficient variable intersection chord length method for quantitative proton CT (pCT) image reconstruction in order to improve the accuracy of the system matrix.
