New Features of a Fastbus Based Data Acquisition System for Imaging Coronary Arteries

Modifications to the VAX-FASTBUS image data acquisition hardware which have become operational since the 1983 NSS will be described. These include modification of the backplane interconnections to support stable operation at 160 megabytes/second, commissioning of the entire 64 megabyte bulk memory system, and the design of a second high speed FASTBUS master module capable of reading data from FASTBUS bulk memory at 160 megabytes/second and presenting these data to a real-time image display system.
