Physiologically realistic injection signal

"... a physiologically realistic, highly periodic waveform was obtained using a computer controlled, in-house flow phantom (Ref: 8) and stored on audio cassette.

The phantom transducers were coupled to the Doptek transducer through a perspex block similar to that used by Evans (Ref: 3) and the waveform was replayed on a Yamaha KX-530 precision cassette deck at a fixed audio power output."
