Automated report-based chart checking detected residual errors after physics review
An automated report-based chart checker detected residual errors in 37.1% of manually reviewed external beam radiotherapy plans.
Volumetric modulated arc therapy complexity surveillance predicted patient-specific quality assurance results
Aperture irregularity and modulation complexity score were the strongest plan-complexity predictors of patient-specific quality assurance pass rate.
Shared-source toolkit integrated spatially fractionated radiation therapy planning inside Eclipse
A shared-source Eclipse toolkit unified lattice generation, position-aware optimization, and peak-valley dose ratio evaluation for spatially fractionated radiation therapy.
Simulation-free single-fraction radiotherapy was feasible for non-spine metastases
Diagnostic computed tomography-based single-fraction radiotherapy was feasible for selected non-spine palliative metastases, with no grade 3 or higher acute toxicity.
Larger bladder geometry was linked to lower planned bladder dose in prostate radiotherapy
Larger bladder volume was strongly associated with lower planned bladder dose in a static five-fraction prostate radiotherapy analysis.
Carbon fiber-reinforced implants may reduce uncertainty in postoperative spine stereotactic body radiotherapy
Carbon fiber-reinforced polyetheretherketone implants consistently reduced imaging artifacts and dosimetric uncertainty versus titanium, but clinical outcome evidence remains limited.
Automated volumetric modulated arc therapy planning improved organ-at-risk sparing in head and neck radiotherapy
Across 500 clinical cases, automated planning preserved target coverage and was associated with lower doses to multiple critical structures than earlier manual planning.
K-means rapidly optimized isocenters and margins for polymetastatic stereotactic ablative radiotherapy
K-means matched hybrid optimization for margin volume while reducing median computation time from 306.9 seconds to 0.19 seconds.
Off-axis beam optimization reduced lung dose in posterior lung stereotactic body radiotherapy
Off-axis beam optimization preserved target coverage while reducing lung dose and enabling collision-free beam geometry for posterior lung lesions.
Robust optimization reduced organ doses in long-course lung radiotherapy
Robust optimization preserved target coverage while reducing lung, heart, esophageal, spinal cord, and estimated immune-cell dose during long-course lung radiotherapy.
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.
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.
Ultrahigh dose-rate radiotherapy still requires conformal planning and conservative dose constraints
Normal-tissue sparing with ultrahigh dose-rate radiotherapy remains conditional and cannot replace conformal dosimetry, organ-at-risk constraints, or rigorous quality assurance.
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.
