Photon minibeams enable denser LATTICE patterns in small tumors
Mini-LATTICE created more compact high-dose vertices and greater peak-to-valley separation than conventional LATTICE across six planning cases.

AI-derived LAD dose reproduced survival stratification in RTOG 0617
Automated LAD contours reproduced the association between coronary dose and survival in 460 stage III NSCLC patients, although performance varied by model.
Deep learning-enhanced registration halves contouring time in daily adaptive prostate MRgRT
A hybrid deep learning–registration workflow reduced median daily prostate MRgRT contouring time from 7.8 to 3.1 minutes while maintaining high contour agreement.
Training-free MRI tracking achieved submillimetre motion accuracy in liver metastases
ETLD tracked 106,000 cine-MRI frames with submillimetre error, while integrated segmentation achieved a mean global Dice score of 87.7%.
Deep learning reduced pediatric craniospinal target contouring from eight hours to 30 minutes
Automated pediatric CSI contours achieved a mean Dice score of 0.959 and reduced target-delineation time from approximately eight hours to 30 minutes.
Deformable registration substantially changed cumulative dose estimates in stereotactic re-irradiation
DIR reduced estimated liver maximum dose from 123.8 to 83.2 Gy, but accuracy deteriorated markedly for bowel and stomach.
An LLM agent generated head and neck IMRT plans comparable to clinical plans
Reference-free LLM planning improved hotspot control and boost-target conformity while maintaining organ-at-risk sparing comparable to clinical plans.
Two-dimensional TCP modeling linked lung tumour control mainly to radiosensitivity heterogeneity
Inter-patient radiosensitivity explained 85–97% of modeled TCP steepness, while uncertainty in delivered dose exceeded uncertainty in local-control estimates.
Expiratory-phase CBCT reduced respiratory blurring during pancreatic SBRT
Repeated end-expiratory breath-hold CBCT achieved boundary sharpness statistically equivalent to daily CT in 10 pancreatic SBRT patients.
High-density shielding materials reduced modeled radiotherapy vault footprint by up to 34%
Alternative shielding materials reduced modeled linac vault area by 17–34% while remaining below the NCRP controlled-area dose goal.
Unshielded SunSILICON detector performed reliably for small-field photon dosimetry
The unshielded SunSILICON detector required only modest corrections in small fields, while the shielded version became unreliable below approximately 2 cm.
Vergence-based planning predicted major astigmatism reduction after toric lens realignment
Model-predicted 16–18° lens rotations reduced residual refractive cylinder by 1.7–2.4 D across four representative clinical scenarios.
Radiotherapy 3D printing needs standardized quality assurance across institutions
Inter-centre material variability supports shared QA datasets and standardized acceptance criteria for clinical radiotherapy 3D printing.
Surface monitoring detected clinically relevant motion in head and neck radiotherapy
SGRT triggered verification in 15% of head and neck fractions, but almost half of alerts were not confirmed on X-ray imaging.
CT–MRI fusion improved contrast-free lung perfusion mapping for radiotherapy planning
Multimodal CT–MRI perfusion maps matched SPECT better than single-modality methods and reduced high-function lung dose in exploratory planning.
