Direct-to-treatment (DTT) streamlines simulation, planning, QA and treatment into same-day, risk-managed pathways that start from diagnostic imaging or treatment-unit imaging. Clinical and physics evidence now supports multiple entry points: diagnostic-CT bas...

Online adaptive stereotactic body radiation therapy (SBRT) reduces organ at risk (OAR) dose for abdominal targets with highly variable anatomy but significantly increases treatment time and clinical workload. Adaptive workflows are routinely assigned to left...

To validate the Exradin W2 plastic scintillator for measuring beam profiles in Leksell Gamma Knife (LGK) quality assurance and to compare its characteristics against MicroDiamond detector measurements as a filmless QA alternative.

Multi-plane target tracking in 0.35 T MR-guided radiotherapy (MRgRT) is beginning to emerge in clinical practice. To support safe implementation, robust and repeatable quality assurance (QA) procedures are needed. This study proposes a practical QA methodolog...

Online adaptive stereotactic body radiation therapy (SBRT) enables daily replanning to mitigate anatomic variation but increases treatment time and clinical workload. For left adrenal tumors, adaptive SBRT is frequently assigned due to the proximity of gastro...

The Stop-Scan-Adapt (SSA) feature introduced with the MRIdian A3i upgrade enables intra-fractional adaptation during online MR-guided adaptive radiotherapy (ART) through re-optimization without patient repositioning. While SSA efficiently responds to intra-fr...
