Perfint Healthcare’s Maxio is a robotics based system for guided oncology procedures. In combination with a CT scan database, Maxio assists Surgical Oncologists with targeting and automated path guidance for Radiofrequency Ablation.  The fully-functional device was in its FDA clinical study stage, and the proposed refinements to the interface were driven from initial (formative) usability feedback.

Multiple areas of the design were identified that lead to confusion within the test group.  These included navigational and interaction issues as well as graphic clarity and information hierarchy issues.  These issues were addressed by developing new flow charts, wireframes and revised iconography. More visual attention was given to the primary prompt window (Message Bar) and users were led through processes via the Stage display.
