Abstract
Task analysis in diagnostic medical sonography is a difficult topic in terms of definition, description at the practical level and differences between clinical applications. The present work describes the task analysis of 28 Diagnostic Ultrasound systems in several clinical applications, 15 systems used by sonographers (USA) and 13 systems used by physicians (Europe). The tests performed demonstrated the different workflow peculiarities of sonographers and physicians, showing how the former have a more complex workflow, which puts more stress on the system user interface optimization and ease of use. The sonographers’ workflow, characterized by an average 23% longer scanning time per exam and 88% greater number of controls activated per exam, may also have a greater induction to develop work-related musculoskeletal disorders, with respect to physician users of US systems.
