OverviewAI-generated summary

W Hsi's research program investigates advanced applications in medical imaging and radiotherapy, with a focus on improving cancer treatment efficacy and understanding treatment-related toxicities. Recent publications explore the use of dual-energy spectral CT for assessing treatment response in head-neck cancers and PET-CT based dose verification in carbon-ion radiotherapy for choroidal melanoma. Studies also address the evaluation of machine-learning models to predict late sciatic nerve toxicity following carbon-ion radiotherapy and the development of planning strategies for intensity-modulated proton therapy in head-neck cancers. Further work examines anatomical changes in the male pelvis to inform prostate treatment positioning and the dosimetric uncertainties associated with spot-scanning carbon-ion and proton radiotherapy.
