The increased application of digital imaging techniques to diagnostic cardiology requires the resolution of several remaining problems involving the transmission, display and storage of clinical image data. A Digital Imaging Laboratory is being assembled for the purpose of addressing these problems on a routine clinical basis in a high volume environment. The laboratory consists of independent work-stations connected over a local area network which can be accessed by different users for display, analysis and storage of diagnostic image data. In addition, the laboratory is connected to a hospital-wide network, providing communication with other clinical laboratories and other digital imaging modalities.
