| Abstract(in English) | Airborne 40KHz ultrasound Doppler systems are devised to monitor and measure variety of moving target investigation in biomedical research fields. Major application, but not limited to, is to measure urea flow running in air. It makes an alternative new method for unconstrained, natural urodynamics study for urology. Other than urodynamics study the device can take up interesting Doppler signals from moving hand, aspiration/respiration air jet, running water droplets including rain, and bicycle to ground speed, etc (2). The device is basically wearable structure and has a finger-mounted transducer. The urea Doppler signal is frequency spectrum analyzed to yield an almost compatible flowmetry to conventional mess-cup type uroflow meter/recorder. CW-Doppler design and pulsed-Doppler design are tried for comparison, however, unexpectedly, for running urea they didn't yield much different kind of signal due to limited bandwidth of the transducer. |
