Automatic support of virtual leaves in Elements offers improved dose conformity in radiosurgery

Brainlab Introduces New Hi-Res Planning Algorithm for VersaHD

April 24, 2018 — Brainlab announced the implementation of a software solution that can achieve better radiation therapy dose conformity around brain tumors, resulting from a close strategic collaboration with Elekta. Brainlab Elements take advantage of the specific properties of Elekta’s Agility multileaf collimator and compensates for the width of selected leaves, enabling the radiation beam to more accurately conform to the tumor’s shape, thereby minimizing dose to organs at risk.

A new treatment planning algorithm in Brainlab Elements cranial radiosurgery software supports virtual leaf width capability with Agility on the Versa HD linear accelerator. Through the dynamic manipulation of the Y-Jaws, the algorithm partially blocks the collimator leaves along the vertical edge of a tumor target, which can reduce the collimator leaf down to 1 mm across the full treatment field of view for enhanced conformity.

Elekta also has an ongoing interoperability program with Brainlab that will ensure integration of ExacTrac 5.x and 6.x as well as future versions.

The new enhanced capability supporting VersaHD builds on the success of existing collaborations between Elekta and Brainlab, like the jointly marketed Leksell Vantage Stereotactic System with Elements Stereotaxy, as well as the integration of Versa HD and Brainlab ExacTrac patient positioning and monitoring technology.
