Design and clinical evaluation of a high capacity digital image archival library and high speed network for the replacement of cinefilm in the cardiac angiography environment


Conference Paper

© 1993 SPIE. All rights reserved. An economical and practical digital solution for the replacement of 35mm cinefilm as the archive media in the cardiac x-ray imaging environment has remained lacking to date due to the demanding requirements of high capacity, high acquisition rate, high transfer rate, and a need for application in a distributed environment. A clinical digital image library and network based on the D2 digital video format has been installed in the Duke University Cardiac Catheterization Laboratory. The system architecture includes a central image library with digital video recorders and robotic tape retrieval, 3 acquisition stations, and remote review stations connected via a serial image network. The library has a capacity for over 20,000 Gigabytes of uncompressed image data, equivalent to records for approximately 20,000 patients. Image acquisition in the clinical laboratories is via a real-time digital interface between the digital angiography system and a local digital recorder. Images are transferred to the library over the serial network at a rate of 14.3 Mbytes/sec and permanently stored for later review. The image library and network are currently undergoing a clinical comparison with cinefilm for visual and quantitative assessment of coronary artery disease. At the conclusion of the evaluation, the configuration will be expanded to include 4 additional catheterization laboratories and remote review stations throughout the hospital.
