Abstract

Managing information flow and workflow in medical imaging services includes mapping activities in medical imaging services to a set of discrete steps in a model medical imaging process. Data concerning the medical imaging services is collected and tracked using an electronic data store and a communications network. Collected data is correlated to at least one of the discrete steps in the model medical imaging process and process metrics for performance are calculated based upon the correlated data.
