An inhomogeneous most likely path formalism for proton computed tomography
Mark Brooke, Scott Penfold
Purpose: Multiple Coulomb scattering (MCS) poses a challenge in proton CT (pCT) image reconstruction. The assumption of straight paths is replaced with Bayesian models of the most…
Sparsity constrained split feasibility for dose-volume constraints in inverse planning of intensity-modulated photon or proton therapy
S. Penfold, R. Zalas, M. Casiraghi +3
A split feasibility formulation for the inverse problem of intensity-modulated radiation therapy (IMRT) treatment planning with dose-volume constraints (DVCs) included in the plann…
Techniques in Iterative Proton CT Image Reconstruction
Scott Penfold, Yair Censor
This is a review paper on some of the physics, modeling, and iterative algorithms in proton computed tomography (pCT) image reconstruction. The primary challenge in pCT image recon…
Total variation superiorization schemes in proton computed tomography image reconstruction
S. N. Penfold, R. W. Schulte, Y. Censor +1
Purpose: Iterative projection reconstruction algorithms are currently the preferred reconstruction method in proton computed tomography (pCT). However, due to inconsistencies in th…
