Elekta integrates hallmark Elekta Synergy® image-guided workflow in the advanced Elekta Infinity system, a comprehensive treatment system that includes Volumetric Modulated Arc Therapy (VMAT). Combining superior dose conformance and treatment speed, VMAT enables clinicians to “shrink wrap” the dose around a tumor by simultaneously manipulating the gantry position and speed, MLC leaves, dose rate and even collimator angle.
3-D image guidance complements VMAT’s speed (< 2 min. to 5 min.) by providing the clinical confidence to visualize targets with the patient in the treatment position minutes before therapy. Integrated imaging enables clinicians, on a daily basis, to correct patient setup errors due to organ motion and increase treatment accuracy. Imaging includes a variety of 2D, 3D and 4D X-Ray Volume Imaging (XVI) tools.
Infinity offers a choice between single or multiple arcs – typically depending on the treatment site – to optimize the VMAT plan. Infinity with VMAT requires much fewer MU’s than with conventional methods, reducing total MU delivery by up to 50 percent. With its new MLC, Infinity optimizes VMAT delivery by limiting interleaf and overall patient leakage for lower dose volumes to critical structures.
