It was studied the application of VMAT technique (Volumetric Modulated Arc Therapy) with a multileaf collimator of 120 leafs, for implementation of this technique as an alternative to stereotactic radiosurgery. To achieve this goal, treatment plans (simulations) were made under VMAT technique using inverse planning and furthermore the physical verification of these plans to 10 patients with multiple brain metastases and primary tumor controlled, finding an acceptable conformation index for this modality (comparable to radiosurgery) in lesions with 1,5cm or more. The doses of radiation in the healthy organs were below the tolerance dose in all cases.
