Stereotactic radiosurgery (SRS) is increasingly being used to manage solitary or multiple brain metastasis. This study aims to compare and validate Anisotropic Analytical Algorithm (AAA) and AcurosXB (AXB) algorithms of Eclipse Treatment Planning System (TPS) in RapidArc-based SRS plans of patients with solitary brain metastasis. Twenty patients with solitary brain metastasis who have been already treated with RapidArc SRS plans calculated using AAA plans were selected for this study.

The accuracy of the dose calculation depends on the treatment planning algorithm. This study is a retrospective dosimetric comparison of iPlan Monte Carlo (MC) and Pencil Beam (PB) algorithms in SRS/SRT plans of cranial arteriovenous malformations (AVMs).

This is a retrospective analysis of 60 clinical treatment plans of arteriovenous malformation (AVM) patients to study clinical usefulness of selected plan quality metrics.
Materials And Methods: The treatment coverage parameters Radiation Therapy Oncology Group (RTOG) Conformity Index (CI), RTOG Quality of Coverage (Q), RTOG Homogeneity Index (HI), Lomax Conformity Index (CI), Paddick's Conformity Index (CI), and dose gradient parameters Paddick's Gradient Index (GI) and Equivalent Fall-off Distance (EFOD) were calculated for the cohort of patients.
