RTsafe

RTsafe is a private medical technology company focused on radiation oncology quality assurance and patient safety. The company develops and commercializes patient-specific and generic 3D-printed dosimetry phantoms, remote dosimetry services, and end-to-end treatment verification tools used by radiotherapy clinics and equipment manufacturers. Its flagship PseudoPatient platform uses real patient anatomical data and 3D printing to simulate radiotherapy workflows before treatment is delivered, with a particular early focus on brain radiotherapy. RTsafe has FDA-cleared personalized phantom technology, operates internationally from Greece with additional presence in the United States and Ireland, and serves hospitals, academic centers, and radiotherapy professionals. The business is best characterized as a commercial medtech platform company rather than a drug developer.
