Liao R, F Williamson J, Xia T, Ge T, A OSullivan J
Phys Med Biol . 2025 Jan; 70(5). PMID: 39746299
Deformable image registration (DIR) is critical in many medical imaging applications. Diffeomorphic transformations, which are smooth invertible mappings with smooth inverses preserve topological properties and are an anatomically plausible means...

Ge T, Liao R, Medrano M, Politte D, F Williamson J, A OSullivan J
Phys Med Biol . 2023 Oct; 68(24). PMID: 37802071
Over the past several decades, dual-energy CT (DECT) imaging has seen significant advancements due to its ability to distinguish between materials. DECT statistical iterative reconstruction (SIR) has exhibited potential for...

Ge T, Liao R, Medrano M, Politte D, Whiting B, F Williamson J, et al.
Phys Med Biol . 2023 Jun; 68(14). PMID: 37327796
Dual-energy computed tomography (DECT) has been widely used to reconstruct numerous types of images due its ability to better discriminate tissue properties. Sequential scanning is a popular dual-energy data acquisition...

Medrano M, Liu R, Zhao T, Webb T, Politte D, Whiting B, et al.
Med Phys . 2022 Jan; 49(3):1599-1618. PMID: 35029302
Purpose: To assess the potential of a joint dual-energy computerized tomography (CT) reconstruction process (statistical image reconstruction method built on a basis vector model (JSIR-BVM)) implemented on a 16-slice commercial...

Liu R, Zhang S, Zhao T, A OSullivan J, F Williamson J, Webb T, et al.
Med Phys . 2020 Dec; 48(2):852-870. PMID: 33296513
Purpose: To investigate via Monte Carlo simulations, the impact of scan subject size, antiscatter grid (ASG), collimator size, and bowtie filter on the distribution of scatter radiation in a typical...

Darafsheh A, Hao Y, Zwart T, Wagner M, Catanzano D, F Williamson J, et al.
Med Phys . 2020 May; 47(9):4348-4355. PMID: 32452558
Purpose: It has been recently shown that radiotherapy at ultrahigh dose rates (>40 Gy/s, FLASH) has a potential advantage in sparing healthy organs compared to that at conventional dose rates....
