Assessing Gamma Index Sensitivity to Selected Linear Accelerator Mechanical Errors Using Various Dosimetric Systems

Background: Volumetric modulated arc therapy (VMAT) for stereotactic body radiotherapy (SBRT) involves highly modulated dose distributions and steep dose gradients, increasing the importance of patient-specific quality assurance (QA). Gamma index analysis is widely used for compa...
