December 30, 2013 — RaySearch Laboratories and TomoTherapy Inc. (now Accuray) entered a software licensing and development agreement in 2007, under which RaySearch developed a product named SharePlan. TomoTherapy launched Shareplan in 2009.
SharePlan is a treatment planning solution that enables transfer of treatment plans between TomoTherapy systems and conventional linear accelerators. The product uses algorithms to automatically generate a selection of deliverable intensity-modulated radiation therapy (IMRT) plans based on an existing TomoTherapy treatment plan. This time-saving concept is a tool for optimizing patient benefit and throughput at clinics that have a mixed environment with both TomoTherapy systems and conventional linear accelerators.
Now RaySearch and Accuray have agreed to cancel the agreement and end the partnership. SharePlan functionality will continue to be available for new and existing customers as an integrated module in RaySearch’s RayStation treatment planning system that is sold and marketed by RaySearch. Existing SharePlan customers will be offered a free upgrade to RayStation.
“Since the original agreement was signed, a lot has changed for both companies, so this solution makes good sense for both parties,” said Johan Löf, CEO, RaySearch. “RayStation was not available four years ago, so back then a stand-alone application was the best solution. Now however, we can offer the same functionality in RayStation, which is evolving very rapidly and also gives the TomoTherapy System users the option to select other features and advanced treatment planning tools. This is attractive for the customers and Accuray alike, as it expands the product offering for these customers.”
