German software-driven medical technology developer Brainlab has entered into an intellectual property license agreement with Atlantic Canada’s leading research-intensive Dalhousie University for an integration with the next generation radiosurgery software.

The new radiosurgery software can be customised in accordance with the patient’s needs, its optimised arc-trajectories are aimed at decreasing the radiation dose emitted to organs infected without compromising on target coverage.

The new algorithms of the software create a suitability ranking for every gantry and couch-position based on geometric overlap of multiple risk organs and the target volume, and takes into consideration the relative depth of structures and dose tolerances.

The algorithm can supplement regions of approach which allow the most rapid dose fall-off toward specific organs at risk. The optimisation can be applied to fixed couch arcs as well as simultaneous gantry-couch movements.

"For patients, this means that we can further limit dose to healthy organs surrounding the tumour, without extending treatment times."

Dalhousie University medical physics chief James Robar said: "We have developed an effective method for trajectory based treatment planning and delivery, often referred to as the four-Pi approach.

"In addition to minimising peripheral dose, the new algorithm alleviates the need for beam modulation, increasing the efficiency of planning and treatment delivery.
