RaySearch Laboratories AB (publ) announced the release of the first version of the treatment control system (TCS) RayCommand[®], and that the system received first market clearances in Europe on December 23, 2020. RayCommand is the link between the treatment machine and the treatment planning and oncology information systems. It coordinates and orchestrates the different systems involved in patient treatment, such as imaging systems, beam delivery systems and the patient support system. Effective coordination is critical to achieve safe and efficient patient treatments. RayCommand was developed in close collaboration with Advanced Oncotherapy (AVO), the UK-based developer of next-generation proton therapy technology, and Austria's MedAustron, one of the world's most advanced cancer centers. RayCommand is an important extension of RaySearch's innovative product portfolio. The development of a cutting-edge TCS broadens the company's capabilities, in line with its ambition to improve patient care through the entire cancer treatment process. The idea to develop a TCS resulted from a collaboration agreement between RaySearch and AVO to develop a comprehensive software solution for the proton therapy system AVO LIGHT. By synchronizing the TCS, treatment planning system (TPS) and oncology information system (OIS), clinics can more efficiently coordinate and orchestrate the multitude of systems involved in cancer treatment, including imaging, beam delivery and patient support. RaySearch's development of RayCommand sparked a great deal of interest from other industrial and clinical partners, including MedAustron, a leading Austrian center specializing in ion radiation therapy and research. MedAustron operates a synchrotron-based accelerator facility for cancer treatment built in Wiener Neustadt, 50 km south of Vienna, Austria.
