Interinstitutional Plan Quality Assessment of 2 Linac-Based, Single-Isocenter, Multiple Metastasis Radiosurgery Techniques.

ABSTRACT:

Purpose

Interest and application of stereotactic radiosurgery for multiple brain metastases continue to increase. Various planning systems are available for linear accelerator (linac)-based single-isocenter multiple metastasis radiosurgery. Two of the most advanced systems are BrainLAB Multiple Metastases Elements (MME), a dynamic conformal arc (DCA) approach, and Varian RapidArc (RA), a volumetric modulated arc therapy (VMAT) approach. In this work, we systematically compared plan quality between the 2 techniques.

Methods and materials

Thirty patients with 4 to 10 metastases (217 total; median 7.5; V_min = 0.014 cm³; V_max = 17.73 cm³) were planned with both Varian RA and MME at 2 different institutions with extensive experience in
