The Materialise Mimics Viewer application for HoloLens allows you to experience surgical and procedural 3D planning use cases in augmented reality. The application contains a variety of clinical demonstration cases of 3D planning, 3D printed guides or personalized implants. It covers several clinical domains, from orthopedics to cranio-maxillofacial surgery and structural heart interventions. The app allows to educate yourself, patients or students about the use of 3D technology in surgical or interventional treatment based on real examples. All use cases in the application are the results of a clinical service or software provided by Materialise. In case of specific questions related to any of the use cases, please reach out via medical@materialise.com. Materialise customers can apply to an early access program and load their own cases in the application.
