Modernizing an ablation UI console

A medical device company's microwave ablation system for interventional radiology and oncology, undergoing a console UI modernization, consolidating a legacy two-screen, dual-arm configuration into a single consolidated display for use in the IR suite. Confidential client (NDA).
Identify HFE risk and establish design direction for a display consolidation that could not alter workflow, functionality, or layout, while satisfying IEC 60601-1-8 alarm color constraints and ensuring critical numeric readouts remained legible during active procedures.
Conducted systematic review of all UI states and hardware photographs, identifying use-error risks across visual hierarchy, alarm system conflicts, distance legibility, and button differentiation. Produced an eight-dimension Design Trend Brief and Ablation Screen Spec Addendum with options-based direction, per-option considerations, and a decision-tracking column.
- •Identified 9+ specific UI safety observations across formative review
- •Identified safety-critical display state conflicts across alarm presentation and error notification
- •Delivered structured options tables across palette, typography, and button system enabling the engineering and design team to evaluate direction against live mockups without blocking design velocity
