Abstract
In this paper we describe a system for the digitization, display, and storage of radiographic images. The system was set up to support a project to assess the clinical impact of matrix size on teleradiology, defined for our purposes as the electronic recording and transmission of radiographs. The system consists of two separate facilities, one for image digitizing and the other for image display, interpretation, and archiving. The image digitizing laboratory uses a solid state scanner interfaced to a dedicated, general-purpose minicomputer. The display facility consists of a general-purpose, multi-user minicomputer with large main memory and disk capacity and a 1280 by 1024 display subsystem with three separate image memories. The two facilities communicate via magnetic tape. This paper documents the characterization of the image data base used for the project, the design and operational features of the two facilities, technical problems encountered in the digitizing and display of radiographs, and some logistical and managerial considerations involved in generating and maintaining a large digital image archive. Since many of the functions of the system we have set up are common to picture archiving and communication systems, we have, where possible, compared the performance of the system we have developed with the requirements that would have to be satisfied by a system intended for clinical use. We leave for future reports the discussion of the conduct of the image reading experiments and the results of those experiments.
