Abstract :
An airborne 40KHz ultrasound Doppler system is devised to monitor and measure urea flow running in air. This is an alternative new method for unconstrained, natural urodynamics study for urology. The device is basically wearable structure and has a finger-mounted transducer. Its signal is frequency spectrum analyzed to yield an almost compatible flowmetry to conventional mess-cup type uroflow meter/recorder.
