CyberKnife reduced low-dose exposure in left-sided partial-breast irradiation
CyberKnife improved conformity and reduced cardiac, pulmonary, and low-dose exposure, while noncoplanar linac techniques remained clinically acceptable alternatives.
Knowledge-based prostate planning transfers across fractionation regimens with comparable plan quality
A conventional-fractionation model produced clinically acceptable moderately hypofractionated prostate plans, with comparable overall quality and slightly reduced target homogeneity.
Commercial lung phantom density errors can reduce target coverage by 3%
Lot-to-lot density variation in lung-equivalent inserts reduced planning target volume coverage by up to 3%, exceeding the stated clinical tolerance.
Low monitor unit deliveries show pulse-limited variability on a modern linear accelerator
Discrete pulse counts limited fractional monitor unit precision, particularly for high-dose-per-pulse flattening filter-free beams.
Ultrahigh dose-rate protons reduce hydrogen peroxide yield in water
Hydrogen peroxide production decreased as proton dose rate increased, with Geant4-DNA simulations reproducing the oxygen-dependent experimental trend.
Monocular surface imaging enables real-time breast dose reconstruction
Patient-specific surface imaging reconstructed breast radiotherapy dose with a 93.8% gamma passing rate and 42-millisecond latency without additional imaging radiation.
Reference beam data may streamline commissioning but cannot replace local validation
Reference datasets can support linear accelerator beam modelling, but machine-specific measurements remain essential for small fields, complex delivery, and long-term verification.
Neutron background limits prompt-gamma range verification in carbon-ion therapy
Prompt-gamma profiles tracked beam range, but stronger neutron backgrounds reduced retrieval precision for carbon ions under clinically relevant conditions.
Machine-specific timing model improves synchrotron proton spot delivery prediction
Measured multi-energy extraction characteristics enabled accurate delivery-time prediction across 605 clinical proton fields, supporting more reliable interplay simulations.
Explainable machine learning predicts structure-specific quality assurance performance in intensity-modulated radiotherapy
Anatomy- and dose-based machine learning predicted gamma passing rates accurately for organs at risk, but less reliably for target volumes.
Dual-scan conformal cone-beam computed tomography improves target-region image quality
Dynamic collimation improved target-region contrast and signal-to-noise ratio while preserving full-field information without increasing the total photon budget.
Semi-automated needle planning shortens cervical brachytherapy workflow while preserving clinical coverage
Semi-automated trajectory planning reduced workflow time and needle use while maintaining clinically acceptable target coverage and organ-at-risk doses.
Patient-led genital positioning improved comfort and modesty during thigh sarcoma radiotherapy
A reusable positioning pouch displaced the genitalia from the treatment field while receiving high satisfaction ratings from patients and radiation therapists.
Four-dimensional prompt-gamma imaging detected proton range changes during pancreatic treatment
Four-dimensional prompt-gamma imaging detected clinically relevant proton range shifts associated with anatomical change during pancreatic proton therapy.
