DYN'R Medical Systems

DYN'R Medical Systems is a private French medical device company focused on respiratory motion management for radiation oncology. Its flagship commercial product, the SDX Respiratory Gating System, is an FDA-cleared, spirometry-based breathing control system used to synchronize imaging and radiotherapy with patient respiration, including breath-hold and free-breathing workflows. The technology is used in conventional radiotherapy, stereotactic body radiotherapy, and proton therapy to improve targeting precision and reduce radiation exposure to healthy tissue. Founded in 1987, the company originated in respiratory pathology management and later expanded into oncology, where SDX has been deployed in cancer treatment centers globally. DYN'R also collaborates with radiation therapy ecosystem partners to adapt its technology to new treatment settings such as upright radiotherapy.
