Radiation therapy software developer RaySearch Laboratories has released an upgraded version of its treatment planning software, RayStation 11B.
Radiation therapy software developer RaySearch Laboratories has released an upgraded version of its treatment planning software, RayStation 11B.
RayStation 11B features improved dose calculation accuracy based on daily conebeam CT images for photon therapy. It now includes two new algorithms that create synthetic CT images using original CT data and daily conebeam CT data.
The software also converts physical dose estimates to biological equivalent dose EQD2 (equivalent dose in 2-Gy fractions) -- an important capability for planning and evaluating treatment -- and helps assess linear energy transfer for proton and other light ion treatment plans, the company said.
![Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD). Top row: Images in a 68-year-old male patient with higher 10-year mean ambient air pollution exposure (7.9 μg/m3 for particulate matter measuring ≤2.5 μm in diameter [PM2.5] and 17.4 parts per billion [ppb] for NO2) with extensive CAD (coronary artery calcium score [CACS] >1,000 and obstructive CAD [≥70% diameter stenosis]). Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
