Precision radiotherapy, which accurately delivers the dose on a tumor and confers little or no
irradiation to the surrounding normal tissue and organs, results in maximum tumor control …

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 …

Proton computed tomography (pCT) has been proposed as an alternative to x-ray computed
tomography (CT) for acquiring relative to water stop** power (RSP) maps used for proton …

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

Purpose Uncertainty in computed tomography (CT)-based range prediction substantially
impairs the accuracy of proton therapy. Direct determination of the stop**-power ratio …

X-ray computed tomography (CT) is widely used in various fields, including medical,
industrial, and fundamental scientific applications. Its quick ability to provide three …

Background and purpose Stop**-power ratios (SPRs) are used in particle therapy to
calculate particle range in patients. The heuristic CT-to-SPR conversion (Hounsfield Look …

Purpose In intensity‐modulated proton therapy (IMPT), protons are used to deliver highly
conformal dose distributions, targeting tumors, and sparing organs‐at‐risk. However, due to …

Despite extensive research in dual-energy computed tomography (CT), single-energy CT
(SECT) is still the standard imaging modality in proton therapy treatment planning and, in …

Novel imaging modalities can improve the estimation of patient elemental compositions for
particle treatment planning. The mean excitation energy (I-value) is a main contributor to the …
