Hands-off Ultrasound Technique: Utilizing Simultaneous Modeling to Enhance Ultrasound Training.

Image acquisition can be a challenging component of obtaining ultrasound proficiency. To assist with obtaining the correct image, instructors may take the transducer away or guide the learner's hand. However, this passive form of learning has been suggested to be much less valuable, as it removes learner autonomy and somatosensory cueing. This paper describes the hands-off ultrasound technique, a simultaneous modeling teaching strategy using multimodal feedback to improve ultrasound image acquisition.
