Motion management plays a critical role in radiation therapy for thoracic and abdominal tumors, where respiratory motion can significantly compromise treatment precision. Among available motion-mitigation techniques, respiratory gating offers distinct advanta...

Cone-beam CT (CBCT) acquired on the linear accelerator is being increasingly used beyond image guidance to support simulation and treatment planning workflows. This work reports the clinical implementation, challenges, and solutions associated with CBCT-based...

Lattice radiotherapy (LRT) is a spatially fractionated radiation technique that creates three-dimensional arrays of high-dose vertices within tumor volumes. Current LRT implementations face geometric constraints in small and medium-sized tumors, primarily due...

Adaptive radiotherapy (ART) and personalized ultra‑fractionated stereotactic adaptive radiotherapy (PULSAR) require longitudinal anatomical modeling, deformable image registration (DIR), and dose recalculation and accumulation. While these capabilities are we...

Minibeam radiation therapy (MBRT) is a spatially fractionated technique that produces millimeter-scale dose heterogeneity with promising normal tissue–sparing effects. Implemented using metallic collimators mounted on the accessory tray, MBRT can be delivered...
