MUNICH–Brainlab AG, a leader in cranial SRS software development and Dalhousie University, Atlantic Canada’s leading research-intensive university located in Nova Scotia, Canada, have entered into an exclusive intellectual property license agreement for integration with next generation radiosurgery software.
The exclusive license covers technology for patient tailored, optimized arc-trajectories aim at minimizing radiation dose to organs at risk without compromising target coverage. The new algorithm creates a suitability ranking for every gantry- and couch-position based on geometric overlap of multiple risk organs and the target volume, and considers the relative depth of structures and dose tolerances. The algorithm can reward regions of approach which allow the most rapid dose fall-off toward specific organs at risk. The optimization can be applied to fixed couch arcs as well as simultaneous gantry-couch movements.
