September 7, 2012 — RaySearch Laboratories AB announces that version 3.0 of RaySearch’s RayStation treatment planning system has been released for clinical use in the European Union, United States, Japan and Australia, and is pending regulatory approval in Canada, China, New Zealand and South Korea. The new version includes a wide range of new features and improvements. RayStation already includes optimization algorithms for VMAT (volumetric modulated arc therapy), IMRT (intensity-modulated radiotherapy) and 3D-CRT (3-D conformal radiotherapy), and version 3.0 adds numerous tools for traditional 3D-CRT planning.
RayStation is designed to handle 4-D adaptive radiation therapy and allows the users to perform dose tracking. This offers the possibility to perform accurate dose accumulation of any delivered or planned dose to any patient geometry using any combination of CT (computed tomography), MRI (magnetic resonance imaging), PET (positron emission tomography) and 4D-CT datasets. RayStation 3.0 closes the whole adaptive loop with full support for adaptive replanning. The treatment planning system lets clinicians monitor the impact of a changing patient geometry as the treatment progresses, and seamlessly adjust and reoptimize the treatment in the same system.
In addition to new features, RayStation 3.0 includes major improvements and performance enhancements that further facilitate and speed up the treatment planning process. One example is the addition of full support for scripting using the IronPython language. This lets users automate large parts of the treatment planning process, which both has the potential to save time and improve consistency. The scripting tools also enable extraction of any relevant patient data point, thereby facilitating advanced studies of large amounts of patient data. Other examples include extensive improvements of the patient modeling workspace, the addition of several new organ models to the integrated model-based segmentation tool, and speed improvements in RayStation’s multi-criteria optimization tools. In addition, the beam commissioning workspace has been re-implemented and tools have been added to facilitate the beam commissioning process, which minimizes the workload for the physics departments in the installation phase.
“We announced the previous version of RayStation in the beginning of this year and we are very proud that we can already release an even stronger product. This development pace really sets us apart, and we have the intention to continue at this pace to further extend our technological lead,” said Johan Löf, CEO of RaySearch.
