Abstract :
An example of a digital signal processor (DSP) as an input/output controller for a digital subtraction angiographic imaging system is presented. The DSP preprocesses the raw data, reducing data volume by a factor of two, and is potentially capable of producing real-time subtracted images for immediate display. The demonstrated utility and power of this technique have made it possible to build, test, and debug a 1200-element system for less than 1.5 times the cost of the previous-600 element system.<>
