Abstract
The preferred embodiments described herein provide a medical diagnostic ultrasound imaging system with a rotatable user interface element having a non-rotatable indicator. In one preferred embodiment, a medical diagnostic ultrasound imaging system user interface is provided with a user interface element comprising a rotatable portion disposed around a non-rotatable portion that comprises an indicator identifying a function of the user interface element. With this preferred embodiment, the indicator does not rotate with rotation of the rotatable portion. In another preferred embodiment, a medical diagnostic ultrasound imaging system is provided with a user interface comprising a rotary input device comprising a rotatable shaft, an inner member disposed around and fixed with respect to the rotatable shaft, and an outer member disposed around the inner member and coupled with the rotatable shaft. The inner member comprises an indicator identifying a function of the rotary input device, and rotation of the outer member rotates the rotatable shaft of the rotary input device without rotating the inner member.
