July 25, 2007 - Selecting the best set of gantry angles for delivering an IMRT treatment can be challenging, even for a skilled dosimetrist. Varian has enhanced its Eclipse treatment planning system with beam angle optimization, a treatment planning tool that automates the process of choosing the best set of beam angles. Beam angle optimization uses sophisticated algorithms to analyze anatomical images and calculate the optimal number and combination of angles for achieving a dose prescription.
