Abstract

The transition from analog film-based to electronic imagery management in radiology departments and clinics requires accurate projection of storage and network capabilities. We previously developed a method of estimating from film usage, static storage requirements for the central archive systems. Planning requires us to project: (a) intermediate (e.g. magnetic disk) storage needs for local area networks and workstations serving clinical care areas, and (b) data transmission rates needed to deliver data to nodes on the network, given the expected dataflows empirically derived in our previous studies. The majority of medical imagery is currently stored on 14'' by 17'' film, each film representing about 6 Mbytes of storage at current standard digitization resolutions. With such applications, initial projections of data rates can be made using records of film usage available in most departments. However, it is also necessary to perform a survey of film users to determine usage of new imagery modalities and comparison imagery requirements in the areas to be served by the network.
