RayStation Version 4.0 Treatment Planning System Released

September 19, 2013 – RaySearch Laboratories AB announced that version 4.0 of RaySearch's RayStation treatment planning system has been released for clinical use in several European countries, USA, Japan, Australia and New Zealand, and is scheduled for market release in Canada, China, and South Korea.

The new version includes a wide range of new features and improvements. For example, RayStation contains a unique solution enabling a more efficient treatment planning process called multi-criteria optimization. This highly intuitive tool lets the clinician evaluate the impact of changing different treatment priorities in real-time, which has a large potential to speed up the time-consuming treatment planning optimization process. With RayStation 4.0 the tool for Multi-criteria optimization is extended with support for creating volumetric modulated arc therapy (VMAT) treatments in addition to intensity-modulated radiotherapy (IMRT). This means that the system stands out as the most intuitive treatment planning system for creating all advanced radiation treatments.

Another new feature in RayStation 4.0 is atlas-based segmentation in the patient modeling module, which is a complement to the existing model-based segmentation tool. Atlas-based segmentation utilizes a structure template framework to create a versatile auto-segmentation tool. It allows the users to create organ atlases from clinical cases and new patients can then be segmented by automatic deformable registration of the best-matching atlas in the clinical database. The geometries in each atlas can be manually contoured or generated with model-based segmentation.

RayStation 4.0 also contains numerous improvements and additions throughout the system such as several added features in 3-D CRT planning including support for static arcs. It offers even faster optimizations due to refined multithreading and improved handling of GUI updates during optimization. In the electron beam design module support has been added for all relevant collimators and the proton beam design module now supports the Mevion S250 machine. For a full list of new features please refer to the release notes.

RayStation 4.0 was demonstrated at the annual American Association of Physicists in Medicine meeting held August 4-8 in Indianapolis, Indiana.
