Designing better radiology workstations: impact of two user interfaces on interpretation errors and user satisfaction.

abstract：:Digital modalities such as CT, MRI, Ultrasound and Computerized Radiography systems, generating softcopy images to be used by a Picture Archiving and Communication System (PACS), need to identify the images properly in order to retrieve and manage them. In many cases, a technologist re-enters patient demographic and s...
