Design of an ergonomic ultrasound system: accommodation of user anthropometrics.

Long-term use of medical imaging devices requires significant improvements to the user experience. One factor that impact upon such experience is whether the device is ergonomically built, ecologically designed, and leverages the current medical practice. In this research, we took a holistic and systematic approach to design an effective and biomechanically-fit ultrasound system. Research methods from behavior science (e.g., contextual inquiry, pseudo experiments) had been adopted to involve the users (sonographers) early in the design process. The end results - product design guideline for a cart type ultrasound system and control panel layout - were reviewed by the users and adjusted so that the design is within the range of an acceptable learning curve while maintaining innovativeness, a differentiated value over competitor's ultrasound devices.
