Aperture-enhanced proton stereotactic radiosurgery reduced normal brain dose compared with photon plans in most cerebral arteriovenous malformation cases.
A thick gas electron multiplier air chamber showed strong dose linearity under conventional and ultra-high dose rate conditions.
Larger bladder volume was strongly associated with lower planned bladder dose in a static five-fraction prostate radiotherapy analysis.
In free-breathing lung stereotactic ablative radiotherapy, posterior drift exceeded the 4-millimetre margin in 15.7% of patients within 20 minutes.
Synthetic stopping power maps showed small target dose differences, but residual range and low-dose gamma errors still require further validation.
Synthetic computed tomography from cone-beam computed tomography achieved a 98.7% gamma pass rate for head-and-neck dose recalculation.
In ten paraspinal chordoma plans, direct cord robust optimization improved coverage and robustness while maintaining acceptable spinal cord doses.
In 180 thoracic proton therapy patients, larger clinical target volume and heart volume independently predicted the need for adaptive replanning.
Simulated proton minibeams preserved spatial fractionation and target homogeneity for targets up to 20 centimetres with depth-adapted beam widths and spacing.
After 66% of couch-angle changes, motion exceeded tolerance, and 0.5-millimetre and 0.5-degree errors reduced near-minimum target dose by 7.6%.
Across 500 clinical cases, automated planning preserved target coverage and was associated with lower doses to multiple critical structures than earlier manual planning.
Mean breast target displacement was below 1.3 mm in every direction, with calculated respiratory margins of approximately 1 mm.
Gastrointestinal motility reduced single-fraction target coverage and broadened organ-at-risk dose ranges, while conventional fractionation substantially attenuated the interplay effect.
The patient-specific framework outperformed three comparison methods and reconstructed respiratory anatomy in 15.6 milliseconds per frame.
Live magnetic resonance imaging–ultrasound fusion achieved under 4 mm registration accuracy and under 5 mm needle localization in two clinical implants.
