The authors describe an electronic numerical digital display system which utilizes light emitting diodes to record contrast medium injection rates on serial angiographic film. The display system is conveniently mounted within the film changer. It was developed to record injection rates during an increasing rate of injection employed in the radiographic "spillover" technique or estimating blood flow.
