Monte Carlo grid size materially changed apparent plan quality in liver SBRT
A 3-mm grid cut Monaco calculation time about threefold but altered target, conformity and dose-falloff metrics despite similar gamma QA.

Small photon fields reduced detected Cherenkov signal despite stable dose-linked production
Detected Cherenkov signal per dose fell sharply in small fields, driven mainly by optical transport rather than major changes in intrinsic Cherenkov production.
Cherenkov light tracked gold implant motion with submillimetre accuracy in water
Cherenkov light imaging tracked gold implant motion in water with submillimetre accuracy during static and volumetric modulated arc therapy delivery.
Optical surface imaging supported Monte Carlo dosimetry for total skin electron therapy
Photogrammetry-derived body surface models enabled Monte Carlo evaluation of total skin electron therapy dose homogeneity and hot-cold spot locations.
A 3D-printed jig enabled small-animal irradiation with clinical iridium-192
A 3D-printed jig delivered approximately uniform iridium-192 tumor dose, delayed tumor growth, and caused no observable short-term radiation toxicity in mice.
Neural model compresses proton Monte Carlo phase-space data while preserving dose accuracy
The neural model reduced phase-space storage from 3 gigabytes to 600 kilobytes while maintaining at least 89.9% gamma passing at 1%/1 mm.
Tissue heterogeneity substantially alters absorbed dose in intraoperative radiotherapy
Absorbed dose near the applicator varied markedly by tissue composition despite accurate Monte Carlo calculation by the treatment planning system.
Macro Monte Carlo accelerates very high energy electron dose calculation with high accuracy
A macro Monte Carlo framework reproduced reference dose calculations for very high energy electron beams up to 250 megaelectronvolts while improving computational efficiency by as much as twenty-sevenfold.
