Pre-treatment CT imaging is a topic of growing importance in particle therapy. Improvements
in the accuracy of stopping-power prediction are demanded to allow for a dose conformality …

Range uncertainty has been a key factor preventing particle radiotherapy from reaching its
full physical potential. One of the main contributing sources is the uncertainty in estimating …

In x‐ray computed tomography (CT), materials with different elemental compositions can
have identical CT number values, depending on the mass density of each material and the …

Over the past decade, spectral or dual‐energy CT has gained relevancy, especially in
oncological radiology. Nonetheless, its use in the radiotherapy (RT) clinic remains limited …

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 …

Purpose Material‐specific imaging and virtual monochromatic imaging/analysis are the two
forms of spectral imaging in CT implemented via either energy‐integration or photon …

Objective: The conditioning (well-posedness) of basis materials (functions) and spectral
channelization play important roles in determining the performance of spectral imaging …

Computed tomography (CT) technology has rapidly evolved since its introduction in the
1970s. It is a highly important diagnostic tool for clinicians as demonstrated by the significant …

Background and Purpose Proton treatment planning relies on an accurate determination of
stopping‐power ratio (SPR) from x‐ray computed tomography (CT). A refinement of the …
