Assessment of elemental decomposition algorithms for particle therapy dose monitoring using positron emission tomography and prompt-gamma imaging

Objective. Accurate dose verification remains a major challenge in particle therapy. Dose monitoring methods such as positron emission tomography (PET) and prompt-gamma (PG) imaging are highly sensitive to uncertainties in tissue composition derived from CT, which can be improved by dual-energy CT (DECT)-based material...

RADMorph: A region-aware deformable registration network for organ-specific thoracic CT alignment.

Deformable image registration plays an important role in radiation therapy, supporting applications such as contour propagation, treatment planning, and motion analysis. However, accurate registration of lung CT images remains challenging in the presence of large respiratory-induced deformations. In this study, we prop...
