Connecting radiologists across
institutions — in real time.

Context
Radnet.kr was a cloud-based health information exchange service designed for the Korean medical market. The core problem: radiologists and clinicians at different institutions had no efficient, standardized way to share medical images and metadata — slowing diagnosis and creating friction in referral workflows.
Design Focus
The project involved shadowing radiologists and hospital administrators to map the existing image-sharing workflow, identifying where handoffs broke down and where delays were introduced. The design addressed both the sharing interface and the real-time reading experience, with particular attention to how agents in the workflow (requesting clinician, receiving radiologist, IT admin) moved through the system with different needs.

Field Research
Contextual inquiry through shadowing gave direct access to how the existing workflow functioned in practice — and where it consistently failed.
