RBWH is the largest medical facility in Queensland and is renowned as a leading cancer center offering a range of advanced treatment approaches. The hospital selected RayStation in 2019 for its cutting-edge features, including adaptive workflow functionality and multi-criteria optimization, which will help keep RBWH at the forefront of cancer treatment.

The first treatments were carried out in January 2021 using the 3DCRT treatment techniqe with Monte Carlo dose calculation.

The radiation therapy team at RBWH comments: "The manual and automatic planning tools in RayStation allowed for a streamlined planning process for the first RayStation patient at RBWH. The capability for site-based templates will ensure efficiency and consistency in planning for patients while maintaining the plan quality we have achieved. Waiting time is minimized due to the fast calculation times for the Monte Carlo dose calculation algorithm. Our first patient required a replan due to significant weight loss at the start of treatment; the ability to track and accumulate delivered dose in RayStation, and to use this as background dose for a replan, proved invaluable."

Johan Löf, founder and CEO, RaySearch, says: "We are pleased to support RBWH in going clinical with RayStation, and we are committed to constant evolution to ensure it remains the leading treatment planning system, with unmatched support for different treatment approaches and delivery systems. Australia is an important market for RaySearch, and we are strengthening our local presence in the country to provide an even higher level of service."
