Experience with a FASTBUS Based Data Acqutisition System for Imaging Coronary Arteries

The design specifications, hardware features, performance, and development costs of a FASTBUS based data acquisition system for transporting image data under the control of a VAX-11/780 computing system are described. The system currently transports digitized images from a television camera running at up to 16 bits per pixel, 512 pixels per scan line, 512 lines per frame, and 30 frames per second via FASTBUS into a large bulk memory by employing no-handshake (MS=3) block transfers at a 148 megabyte/second transfer rate.
