Dosimetric study of split-arc technique based on personalized collimator optimization in VMAT for multiple brain metastases.

PURPOSE To evaluate the multiple split-arc technique in mitigating the "island blocking effect (IBE)" during volumetric modulated arc therapy (VMAT) for multiple brain metastases (MBM) and identify the optimal clinical protocol. METHODS A retrospective analysis of 20 MBM patients (2-5 targets) was performed. Four VMA...

Contrastive adversarial mix-up learning for unsupervised cross-modality image segmentation

Background Unsupervised domain adaptation (UDA) has been extensively investigated in terms of its ability to address the performance degradation caused by distribution shifts between labeled source-domain images and unlabeled target-domain images. In radiotherapy, this problem is particularly relevant for the transfer...

Relevance between patients’ clinical factors and 4D-CT lung ventilation heterogeneity for evaluating the adoption of functional avoidance thoracic radiotherapy with a large patient database

Four-dimensional computed tomography (4D-CT)-guided functional-avoidance radiotherapy reduces radiation pneumonitis, but the lack of patient selection criteria limits its adoption. This study aimed to identify clinical predictors of lung ventilation heterogeneity and determine which patients derive the greatest dos...
