Delft Imaging · CAD4TB Platform UX/UI Redesign

CAD4TB is an AI-powered chest X-ray tool that helps screen and triage tuberculosis in low to middle income countries where access to radiologists, stable internet, and clinical infrastructure is limited.

Led the end-to-end UX/UI redesign of the CAD4TB Platform, a cloud-based digital environment that centralizes data from CAD4TB deployments and lets clients manage sites, users, and studies while monitoring and visualizing screening results across low to middle income countries.

The main challenge was the minimal available UX data and the low digital literacy across key user groups in low- and middle-resource countries. We started by defining persona clusters, user needs, and user flows around real-world constraints such as intermittent connectivity, crowded clinics, and time-pressured workflows. From there, we restructured the information architecture, created wireframes and low-fidelity prototypes, and iterated to reduce cognitive load and simplify core tasks.

Ultimately, we then developed a complex, variant-based prototype in Figma with in-app logic and multiple user paths, enabling a realistic product demo at The Union, our most important annual event for the TB and health-tech community. The prototype received special highlights at the convention, helped drive conversion interest among partners, and now serves as the blueprint for the next-generation CAD4TB product currently in development.
