Volumetric Intensity Modulated Arc Therapy

Elekta’s VMAT - volumetric intensity modulated arc therapy is currently the only fully digital linear accelerator with 3D volumetric imaging and advanced treatment planning expertise. Through this new intensity-modulated radiation therapy (IMRT) treatment technique VMAT spares healthy tissue and delivers target coverage and patient safety. Treatment planning for Elekta VMAT is similar to planning for conventional intensity modulated radiation therapy. Physicians have the choice of delivering VMAT - volumetric intensity modulated arc therapy using a single arc, multiple arcs, partial arcs, or a combination of them. Elekta’s VMAT - volumetric intensity modulated arc therapy needs shorter treatment time than other intensity modulated radiation therapy (IMRT) techniques. Daily 3D volumetric imaging and fewer MUs are allowed with volumetric intensity modulated arc therapy. VMAT - volumetric intensity modulated arc therapy has helical-like IMRT conformity and dose distribution.
