Abstract

A modular real-time video processing system has been constructed and is currently being used for angiographic applications. The novel feature of this system is the multiple video bus and the accompanying modular design. The system consists of a number of independent modules ; memory, control, input/output, and arithmetic processors. These modules communicate with one another over a number of video pathways, under the controlof an 8-bit microprocessor. The system architecture and control structure will be described. At present, the system is configured to perform certain operations which have been recognized to be useful for digital subtractive angiography. These operations are carried out for each pixel at video rates ; that is, at 14 x 106 pixels per second. The operations include, video averaging, first order recursive filtering, subtraction, and some non-linear filtering. Examples from clinical trials are provided.
