About
W. Hsi is a leading expert in proton therapy dosimetry and treatment delivery, with a particular focus on the precision of field matching and robotic patient positioning. His most cited work, “Validation of dosimetric field matching accuracy from proton therapy using a robotic patient positioning system” (2010, 9 citations), addresses a critical challenge in treating large, shallow target volumes. Hsi demonstrated that while proton therapy offers distinct advantages for such volumes, the narrow beam penumbra at shallow depths makes field matching far more sensitive to misalignment than with electrons or photons. By validating the use of a robotic couch to achieve sub-millimeter positioning accuracy, his research provided a practical, high-precision solution that directly improved the safety and efficacy of proton treatments. This contribution is foundational for clinics implementing advanced delivery techniques, ensuring dose homogeneity at field junctions. Hsi’s work continues to influence quality assurance protocols and the development of automated positioning systems in proton therapy.
