MR-only CyberKnife planning achieved near-equivalent dosimetry for brain metastases
Synthetic CT reproduced CyberKnife target dosimetry closely and enabled submillimetre translational image guidance, although rotational errors were more variable.

CyberKnife dose models found size-dependent but non-monotonic brain metastasis control
Tumour-size strata showed non-monotonic BED–control relationships, while machine-learning performance remained unvalidated outside a single retrospective centre.
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.
