Sofie Tilbæk et al. The article evaluates whether proton therapy can provide superior organ protection while maintaining treatment robustness in patients with high-risk prostate cancer receiving whole-pelvic radiotherapy (WPRT). The study was conducted within a multicenter randomized clinical trial framework and focused particularly on the impact of anatomical and setup variations during treatment, which are […]

  RaySearch: an enhanced support for particle therapy RE-irradiation planning and evaluation. With the upcoming RayStation release, RaySearch introduces a new investigational (not CE-marked or FDA-cleared, thus not available for clinical use) functionality for reirradiation planning and evaluation. The new framework includes cumulative dose assessment based on deformable image registration and equi-effective dose in 2 […]
