Without the need for a 3D scanner and using photogrammetry techniques and low-cost devices, the clinic can provide precise patient information, from which a custom cover for their prosthetic leg is manufactured, providing better alignment to their lifestyle through attractive designs and materials suitable for different activities, and recreating the geometry of their healthy leg on the prosthetic one. The app, in addition to being multi-platform from a single codebase, has solved various technical challenges, such as full integration with ERP business processes, fast synchronization of a large number of heavy photos, and a wizard-guided order process that dynamically adapts to centrally established configurations and requirements.
